Web Application Framework for R

Makes it incredibly easy to build interactive web applications with R. Automatic "reactive" binding between inputs and outputs and extensive pre-built widgets make it possible to build beautiful, responsive, and powerful applications with minimal effort.



Shiny is a new package from RStudio that makes it incredibly easy to build interactive web applications with R.

For an introduction and examples, visit the Shiny Dev Center.

  • Build useful web applications with only a few lines of code—no JavaScript required.
  • Shiny applications are automatically "live" in the same way that spreadsheets are live. Outputs change instantly as users modify inputs, without requiring a reload of the browser.
  • Shiny user interfaces can be built entirely using R, or can be written directly in HTML, CSS, and JavaScript for more flexibility.
  • Works in any R environment (Console R, Rgui for Windows or Mac, ESS, StatET, RStudio, etc.).
  • Attractive default UI theme based on Bootstrap.
  • A highly customizable slider widget with built-in support for animation.
  • Pre-built output widgets for displaying plots, tables, and printed output of R objects.
  • Fast bidirectional communication between the web browser and R using the httpuv package.
  • Uses a reactive programming model that eliminates messy event handling code, so you can focus on the code that really matters.
  • Develop and redistribute your own Shiny widgets that other developers can easily drop into their own applications (coming soon!).

To install the stable version from CRAN, simply run the following from an R console:


To install the latest development builds directly from GitHub, run this instead:

if (!require("devtools"))

To learn more we highly recommend you check out the Shiny Tutorial. The tutorial explains the framework in-depth, walks you through building a simple application, and includes extensive annotated examples.

We hope you enjoy using Shiny. If you have general questions about using Shiny, please use the Shiny mailing list. For bug reports, please use the issue tracker.

Shiny versions and below used the Bootstrap 2 web framework. After, Shiny switched to Bootstrap 3. For most users, the upgrade should be seamless. However, if you have have customized your HTML-generating code to use features specific to Bootstrap 2, you may need to update your code to work with Bootstrap 3.

If you do not wish to update your code at this time, you can use the shinybootstrap2 package for backward compatibility.

If you prefer to install an older version of Shiny, you can do it using the devtools package:

devtools::install_version("shiny", version = "")

The Javascript code in Shiny is minified using tools that run on Node.js. See the tools/ directory for more information.

The shiny package is licensed under the GPLv3. See these files in the inst directory for additional details:

shiny 0.14.2

This is a maintenance release of Shiny, with some bug fixes and minor new features.

  • Added a fade argument to modalDialog() -- setting it to FALSE will remove the usual fade-in animation for that modal window. (#1414)

  • Fixed a "duplicate binding" error that occurred in some edge cases involving insertUI and nested uiOutput. (#1402)

  • Fixed #1422: When using the shiny.trace option, allow specifying to only log SEND or RECV messages, or both. (PR #1428)

  • Fixed #1419: Allow overriding a JS custom message handler. (PR #1445)

  • Added exportTestValues() function, which allows a test driver to query the session for values internal to an application's server function. This only has an effect if the shiny.testmode option is set to TRUE. (#1436)

  • Fixed #1427: make sure that modals do not close incorrectly when an element inside them is triggered as hidden. (#1430)

  • Fixed #1404: stack trace tests were not compatible with the byte-code compiler in R-devel, which now tracks source references.

  • sliderInputBinding.setValue() now sends a slider's value immediately, instead of waiting for the usual 250ms debounce delay. (#1429)

  • Fixed a bug where, in versions of R before 3.2, Shiny applications could crash due to a bug in R's implementation of list2env(). (#1446)

shiny 0.14.1

This is a maintenance release of Shiny, with some bug fixes and minor new features.

  • Restored file inputs are now copied on restore, so that the restored application can't modify the bookmarked file. (#1370)

  • Added support for plot interaction in the development version of ggplot2, Also added support for ggplot2 plots with coord_flip() (in the development version of ggplot2). (hadley/ggplot2#1781, #1392)

  • Fixed #1093 better: updateRadioButtons() and updateCheckboxGroupInput() were not working correctly if the choices were given as a numeric vector. This had been solved in #1291, but that introduced a different bug #1396 that this better fix avoids. (#1370)

  • Fixed #1368: If an app with a file input was bookmarked and restored, and then the restored app was bookmarked and restored (without uploading a new file), then it would fail to restore the file the second time. (#1370)

  • Fixed #1369: sliderInput() did not allow showing numbers without a thousands separator.

  • Fixed #1346 and #1107 : jQuery UI's datepicker conflicted with the bootstrap-datepicker used by Shiny's dateInput() and dateRangeInput(). (#1374)

  • Updated to bootstrap-datepicker 1.6.4. (#1218, #1374)

  • Updated to jQuery UI 1.12.1. Previously, Shiny included a build of 1.11.4 which was missing the datepicker component due to a conflict with the bootstrap-datepicker used by Shiny's dateInput() and dateRangeInput(). (#1374)

shiny 0.14

A new Shiny release is upon us! There are many new exciting features, bug fixes, and library updates. We'll just highlight the most important changes here, but you can browse through the full changelog below for details. This will likely be the last release before shiny 1.0, so get out your party hats!

Shiny now supports bookmarkable state: users can save the state of an application and get a URL which will restore the application with that state. There are two types of bookmarking: encoding the state in a URL, and saving the state to the server. With an encoded state, the entire state of the application is contained in the URL’s query string. You can see this in action with this app: https://gallery.shinyapps.io/113-bookmarking-url/. An example of a bookmark URL for this app is https://gallery.shinyapps.io/113-bookmarking-url/?inputs&n=200. When the state is saved to the server, the URL might look something like: https://gallery.shinyapps.io/bookmark-saved/?state_id=d80625dc681e913a (note that this URL is not for an active app).

Important note:

Saved-to-server bookmarking currently works with Shiny Server Open Source. Support on Shiny Server Pro, RStudio Connect, and shinyapps.io is under development and testing. However, URL-encoded bookmarking works on all hosting platforms.

See this article to get started with bookmarkable state. There is also an advanced-level article (for apps that have a complex state), and a modules article that details how to use bookmarking in conjunction with modules.

Shiny can now display notifications on the client browser by using the showNotification() function. Use this demo app to play around with the notification API. Here's a screenshot of a very simple notification (shown when the button is clicked):

Here's our article about it, and the reference documentation.

If your Shiny app contains computations that take a long time to complete, a progress bar can improve the user experience by communicating how far along the computation is, and how much is left. Progress bars were added in Shiny 0.10.2. In Shiny 0.14, they were changed to use the notifications system, which gives them a different look.

Important note:

If you were already using progress bars and had customized them with your own CSS, you can add the style = "old" argument to your withProgress() call (or Progress$new()). This will result in the same appearance as before. You can also call shinyOptions(progress.style = "old") in your app's server function to make all progress indicators use the old styling.

To see new progress bars in action, see this app in the gallery. You can also learn more about this in our article and in the reference documentation (either for the easier withProgress functional API or the more complicated, but more powerful, Progress object-oriented API.

Shiny can now automatically reconnect to your Shiny session if you temporarily lose network access.

Shiny has now built-in support for displaying modal dialogs like the one below (live app here):

To learn more about this, read our article and the reference documentation.

Sometimes in a Shiny app, arbitrary HTML UI may need to be created on-the-fly in response to user input. The existing uiOutput and renderUI functions let you continue using reactive logic to call UI functions and make the results appear in a predetermined place in the UI. The insertUI and removeUI functions, which are used in the server code, allow you to use imperative logic to add and remove arbitrary chunks of HTML (all independent from one another), as many times as you want, whenever you want, wherever you want. This option may be more convenient when you want to, for example, add a new model to your app each time the user selects a different option (and leave previous models unchanged, rather than substitute the previous one for the latest one).

See this simple demo app of how one could use insertUI and removeUI to insert and remove text elements using a queue. Also see this other app that demonstrates how to insert and remove a few common Shiny input objects. Finally, this app shows how to dynamically insert modules using insertUI.

For more, read our article about dynamic UI generation and the reference documentation about insertUI and removeUI.

Many Shiny users have asked about best practices for accessing external databases from their Shiny applications. Although database access has long been possible using various database connector packages in R, it can be challenging to use them robustly in the dynamic environment that Shiny provides. So far, it has been mostly up to application authors to find the appropriate database drivers and to discover how to manage the database connections within an application. In order to demystify this process, we wrote a series of articles (first one here) that covers the basics of connecting to an external database, as well as some security precautions to keep in mind (e.g. how to avoid SQL injection attacks).

There are a few packages that you should look at if you're using a relational database in a Shiny app: the dplyr and DBI packages (both featured in the article linked to above), and the brand new pool package, which provides a further layer of abstraction to make it easier and safer to use either DBI or dplyr. pool is not yet on CRAN. In particular, pool will take care of managing connections, preventing memory leaks, and ensuring the best performance. See this pool basics article and the more advanced-level article if you're feeling adventurous! (Both of these articles contain Shiny app examples that use DBI to connect to an external MySQL database.) If you are more comfortable with dplyr than DBI, don't miss the article about the integration of pool and dplyr.

If you're new to databases in the Shiny world, we recommend using dplyr and pool if possible. If you need greater control than dplyr offers (for example, if you need to modify data in the database or use transactions), then use DBI and pool. The pool package was introduced to make your life easier, but in no way constrains you, so we don't envision any situation in which you'd be better off not using it. The only caveat is that pool is not yet on CRAN, so you may prefer to wait for that.

There are many more minor features, small improvements, and bug fixes than we can cover here, so we'll just mention a few of the more noteworthy ones (the full changelog, with links to all the relevant issues and pull requests, is right below this section):

  • Error Sanitization: you now have the option to sanitize error messages; in other words, the content of the original error message can be suppressed so that it doesn't leak any sensitive information. To sanitize errors everywhere in your app, just add options(shiny.sanitize.errors = TRUE) somewhere in your app. Read this article for more, or play with the demo app.

  • Code Diagnostics: if there is an error parsing ui.R, server.R, app.R, or global.R, Shiny will search the code for missing commas, extra commas, and unmatched braces, parens, and brackets, and will print out messages pointing out those problems. (#1126)

  • Reactlog visualization: by default, the showReactLog() function (which brings up the reactive graph) also displays the time that each reactive and observer were active for:

    This new feature can be turned off with showReactLog(time = FALSE). This may be convenient if you have a large graph and don't want to have this new information cluttering it up. The elapsed time info shows up above each relevant node's label, and the time is also coded by color: the slowest reactive will be dark red and the fastest will be light red.

    Additionally, to organize the graph, you can now drag any of the nodes to a specific position and leave it there.

  • Nicer-looking tables: we've made tables generated with renderTable() look cleaner and more modern. While this won't break any older code, the finished look of your table will be quite a bit different, as the following image shows:

    For more, read our short article about this update, experiment with all the new features in this demo app, or check out the reference documentation.

  • Progress indicators can now either use the new notification API, using style = "notification" (default), or be displayed with the previous styling, using style = "old". You can also call shinyOptions(progress.style = "old") in the server function to make all progress indicators use the old styling. Note that if you had customized your progress indicators with additional CSS, you'll need to use the old style if you want your UI to look the same (#1160 and #1329).

  • Closed #1161: Deprecated the position argument to tabsetPanel() since Bootstrap 3 stopped supporting this feature.

  • The long-deprecated ability to pass a func argument to many of the render functions has been removed.

  • Added the ability to bookmark and restore application state. (main PR: #1209)

  • Added a new notification API. From R, there are new functions showNotification and hideNotification. From JavaScript, there is a new Shiny.notification object that controls notifications. (#1141)

  • Progress indicators now use the notification API. (#1160)

  • Added the ability for the client browser to reconnect to a new session on the server, by setting session$allowReconnect(TRUE). This requires a version of Shiny Server that supports reconnections. (#1074)

  • Added modal dialogs. (#1157)

  • Added insertUI and removeUI functions to be able to add and remove chunks of UI, standalone, and all independent of one another. (#1174 and #1189)

  • Improved renderTable() function to make the tables look prettier and also provide the user with a lot more parameters to customize their tables with. (#1129)

  • Added support for the pool package (use Shiny's timer/scheduler). (#1226)

  • Added cancelOutput argument to req(). This causes the currently executing reactive to cancel its execution, and leave its previous state alone (as opposed to clearing the output). (#1272)

  • Display: Showcase now displays the .js, .html and .css files in the www directory by default. In order to use showcase mode and not display these, include a new line in your Description file: IncludeWWW: False. (#1185)

  • Added an error sanitization option: options(shiny.sanitize.errors = TRUE). By default, this option is FALSE. When TRUE, normal errors will be sanitized, displaying only a generic error message. This changes the look of an app when errors are printed (but the console log remains the same). (#1156)

  • Added the option of passing arguments to an xxxOutput() function through the corresponding renderXXX() function via an outputArgs parameter to the latter. This is only valid for snippets of Shiny code in an interactive runtime: shiny Rmd document (never for full apps, even if embedded in an Rmd). (#1443)

  • Added updateActionButton() function, so the user can change an actionButton's (or actionLink's) label and/or icon. It also checks that the icon argument (for both creation and updating of a button) is valid and throws a warning otherwise. (#1134)

  • Added code diagnostics: if there is an error parsing ui.R, server.R, app.R, or global.R, Shiny will search the code for missing commas, extra commas, and unmatched braces, parens, and brackets, and will print out messages pointing out those problems. (#1126)

  • Added support for horizontal dividers in navbarMenu. (#1147)

  • Added placeholder option to passwordInput. (#1152)

  • Added session$resetBrush(brushId) (R) and Shiny.resetBrush(brushId) (JS) to programatically clear brushes from imageOutput/plotOutput. (#1197)

  • Added textAreaInput. (thanks, @nuno-agostinho! #1300)

  • Added session$sendBinaryMessage(type, message) method for sending custom binary data to the client. See ?session. (thanks, @daef! #1316 and #1320)

  • Almost all code examples now have a runnable example with shinyApp(), so that users can run the examples and see them in action. (#1158)

  • When resized, plots are drawn with replayPlot(), instead of re-executing all plotting code. This results in faster plot rendering. (#1112)

  • Exported the isTruthy() function. (part of PR #1272)

  • Reactive log now shows elapsed time for reactives and observers. (#1132)

  • Nodes in the reactlog visualization are now sticky if the user drags them. (#1283)

  • Fixed #1350: Highlighting of reactives didn't work in showcase mode.

  • Fixed #1331: renderPlot() now correctly records and replays plots when execOnResize = FALSE.

  • updateDateInput() and updateDateRangeInput() can now clear the date input fields. (thanks, @gaborcsardi! #1299, #1315 and #1317)

  • Fixed #561: DataTables previously might pop up a warning when the data was updated extremely frequently.

  • Fixed #776: In some browsers, plots sometimes flickered when updated.

  • Fixed #543 and #855: When navbarPage() had a navbarMenu() as the first item, it did not automatically select an item.

  • Fixed #970: navbarPage() previously did not have an option to set the selected tab.

  • Fixed #1253: Memory could leak when an observer was destroyed without first being invalidated.

  • Fixed #931: Nested observers could leak memory.

  • Fixed #1144: updateRadioButton() and updateCheckboxGroupInput() broke controls when used in modules (thanks, @sipemu!).

  • Fixed #1093: updateRadioButtons() and updateCheckboxGroupInput() didn't work if choices was numeric vector.

  • Fixed #1122: downloadHandler() popped up empty browser window if the file wasn't present. It now gives a 404 error code.

  • Fixed #1278: Reactive system was being flushed too often (usually this just means a more-expensive no-op than necessary).

  • Fixed #803 and #1179: handling malformed dates in dateInput and updateDateInput().

  • Fixed #1257: updateSelectInput() didn't work correctly in IE 11 and Edge.

  • Fixed #971: runApp() would give confusing error if port was not numeric.

  • Shiny now avoids using ports that Chrome deems unsafe. (#1222)

  • Added workaround for quartz graphics device resolution bug, where resolution is hard-coded to 72 ppi.

  • Updated to ion.RangeSlider 2.1.2.

  • Updated to Font Awesome 4.6.3.

  • Updated to Bootstrap 3.3.7.

  • Updated to jQuery 1.12.4.

shiny 0.13.2

  • Updated documentation for htmlTemplate.

shiny 0.13.1

  • flexCol did not work on RStudio for Windows or Linux.

  • Fixed RStudio debugger integration.

  • BREAKING CHANGE: The long-deprecated ability to pass functions (rather than expressions) to reactive() and observe() has finally been removed.

shiny 0.13.0

  • Fixed #962: plot interactions did not work with the development version of ggplot2 (after ggplot2 1.0.1).

  • Fixed #902: the drag_drop plugin of the selectize input did not work.

  • Fixed #933: updateSliderInput() does not work when only the label is updated.

  • Multiple imageOutput/plotOutput calls can now share the same brush id. Shiny will ensure that performing a brush operation will clear any other brush with the same id.

  • Added placeholder option to textInput.

  • Improved support for Unicode characters on Windows (#968).

  • Fixed bug in selectInput and selectizeInput where values with double quotes were not properly escaped.

  • runApp() can now take a path to any .R file that yields a shinyApp object; previously, the path had to be a directory that contained an app.R file (or server.R if using separately defined server and UI). Similarly, introduced shinyAppFile() function which creates a shinyApp object for an .R file path, just as shinyAppDir() does for a directory path.

  • Introduced Shiny Modules, which are designed to 1) simplify the reuse of Shiny UI/server logic and 2) make authoring and maintaining complex Shiny apps much easier. See the article linked from ?callModule.

  • invalidateLater and reactiveTimer no longer require an explicit session argument; the default value uses the current session.

  • Added session$reload() method, the equivalent of hitting the browser's Reload button.

  • Added shiny.autoreload option, which will automatically cause browsers to reload whenever Shiny app files change on disk. This is intended to shorten the feedback cycle when tweaking UI code.

  • Errors are now printed with stack traces! This should make it tremendously easier to track down the causes of errors in Shiny. Try it by calling stop("message") from within an output, reactive, or observer. Shiny itself adds a lot of noise to the call stack, so by default, it attempts to hide all but the relevant levels of the call stack. You can turn off this behavior by setting options(shiny.fullstacktrace=TRUE) before or during app startup.

  • Fixed #1018: the selected value of a selectize input is guaranteed to be selected in server-side mode.

  • Added req function, which provides a simple way to prevent a reactive, observer, or output from executing until all required inputs and values are available. (Similar functionality has been available for a while using validate/need, but req provides a much simpler and more direct interface.)

  • Improve stability with Shiny Server when many subapps are used, by deferring the loading of subapp iframes until a connection has first been established with the server.

  • Upgrade to Font Awesome 4.5.0.

  • Upgraded to Bootstrap 3.3.5.

  • Upgraded to jQuery 1.12.4

  • Switched to an almost-complete build of jQuery UI with the exception of the datepicker extension, which conflicts with Shiny's date picker.

  • Added fillPage function, an alternative to fluidPage, fixedPage, etc. that is designed for apps that fill the entire available page width/height.

  • Added fillRow and fillCol functions, for laying out proportional grids in fillPage. For modern browsers only.

  • Added runGadget, paneViewer, dialogViewer, and browserViewer functions to support Shiny Gadgets. More detailed docs about gadgets coming soon.

  • Added support for the new htmltools 0.3 feature htmlTemplate. It's now possible to use regular HTML markup to design your UI, but still use R expressions to define inputs, outputs, and HTML widgets.

shiny 0.12.2

  • GitHub changed URLs for gists from .tar.gz to .zip, so runGist was updated to work with the new URLs.

  • Callbacks from the session object are now guaranteed to execute in the order in which registration occurred.

  • Minor bugs in sliderInput's animation behavior have been fixed. (#852)

  • Updated to ion.rangeSlider to 2.0.12.

  • Added shiny.minified option, which controls whether the minified version of shiny.js is used. Setting it to FALSe can be useful for debugging. (#826, #850)

  • Fixed an issue for outputting plots from ggplot objects which also have an additional class whose print method takes precedence over print.ggplot. (#840, 841)

  • Added width option to Shiny's input functions. (#589, #834)

  • Added two alias functions of updateTabsetPanel() to update the selected tab: updateNavbarPage() and updateNavlistPanel(). (#881)

  • All non-base functions are now explicitly namespaced, to pass checks in R-devel.

  • Shiny now correctly handles HTTP HEAD requests. (#876)

shiny 0.12.1

  • Fixed an issue where unbindAll() causes subsequent bindAll() to be ignored for previously bound outputs. (#856)

  • Undeprecate dataTableOutput and renderDataTable, which had been deprecated in favor of the new DT package. The DT package is a bit too new and has a slightly different API, we were too hasty in deprecating the existing Shiny functions.

shiny 0.12.0

In addition to the changes listed below (in the Full Changelog section), there is an infrastructure change that could affect existing Shiny apps.

In Shiny 0.12.0, we've switched from RJSONIO to jsonlite. For the vast majority of users, this will result in no noticeable changes; however, if you use any packages in your Shiny apps which rely on the htmlwidgets, you will also need to update htmlwidgets to 0.4.0. Both of these packages will issue a message when loaded, if the other package needs to be upgraded.

POSIXt objects are now serialized to JSON in UTC8601 format (like "2015-03-20T20:00:00Z"), instead of as seconds from the epoch. If you have a Shiny app which uses sendCustomMessage() to send datetime (POSIXt) objects, then you may need to modify your Javascript code to receive time data in this format.

Shiny 0.12.0 deprecated Shiny's dataTableOutput and renderDataTable functions and instructed you to migrate to the nascent DT package instead. (We'll talk more about DT in a future blog post.) User feedback has indicated this transition was too sudden and abrupt, so we've undeprecated these functions in 0.12.1. We'll continue to support these functions until DT has had more time to mature.

  • Switched from RJSONIO to jsonlite. This improves consistency and speed when converting between R data structures and JSON. One notable change is that POSIXt objects are now serialized to JSON in UTC8601 format (like "2015-03-20T20:00:00Z"), instead of as seconds from the epoch).

  • In addition to the existing support for clicking and hovering on plots created by base graphics, added support for double-clicking and brushing. (#769)

  • Added support for clicking, hovering, double-clicking, and brushing for plots created by ggplot2, including support for facets. (#802)

  • Added nearPoints and brushedPoints functions for easily selecting rows of data that are clicked/hovered, or brushed. (#802)

  • Added shiny.port option. If this is option is set, runApp() will listen on this port by default. (#756)

  • runUrl, runGist, and runGitHub now can save downloaded applications, with the destdir argument. (#688)

  • Restored ability to set labels for selectInput. (#741)

  • Travis continuous integration now uses Travis's native R support.

  • Fixed encoding issue when the server receives data from the client browser. (#742)

  • The session object now has class ShinySession, making it easier to test whether an object is indeed a session object. (#720, #746)

  • Fix JavaScript error when an output appears in nested uiOutputs. (Thanks, Gregory Zhang. #749)

  • Eliminate delay on receiving new value when updateSliderInput(value=...) is called.

  • Updated to DataTables (Javascript library) 1.10.5.

  • Fixed downloading of files that have no filename extension. (#575, #753)

  • Fixed bug where nested UI outputs broke outputs. (#749, #750)

  • Removed unneeded HTML ID attributes for checkboxGroupInputs and radioButtons. (#684)

  • Fixed bug where checkboxes were still active even after Shiny.unbindAll() was called. (#206)

  • The server side selectize input will load the first 1000 options by default before users start to type and search in the box. (#823)

  • renderDataTable() and dataTableOutput() have been deprecated in shiny and will be removed in future versions of shiny. Please use the DT package instead: http://rstudio.github.io/DT/ (#807)

shiny 0.11.1

  • Major client-side performance improvements for pages that have many conditionalPanels, tabPanels, and plotOutputs. (#693, #717, #723)

  • tabPanels now use the title for value by default. This fixes a bug in which an icon in the title caused problems with a conditionalPanel's test condition. (#725, #728)

  • selectInput now has a size argument to control the height of the input box. (#729)

  • navbarPage no longer includes a first row of extra whitespace when header=NULL. (#722)

  • selectInputs now use Bootstrap styling when selectize=FALSE. (#724)

  • Better vertical spacing of label for checkbox groups and radio buttons.

  • selectInput correctly uses width for both selectize and non-selectize inputs. (#702)

  • The wrapper tag generated by htmlOutput and uiOutput can now be any type of HTML tag, instead of just span and div. Also, custom classes are now allowed on the tag. (#704)

  • Slider problems in IE 11 and Chrome on touchscreen-equipped Windows computers have been fixed. (#700)

  • Sliders now work correctly with draggable panels. (#711)

  • Fixed arguments in fixedPanel. (#709)

  • downloadHandler content callback functions are now invoked with a temp file name that has the same extension as the final filename that will be used by the download. This is to deal with the fact that some file writing functions in R will auto-append the extension for their file type (pdf, zip).

shiny 0.11

Shiny 0.11 switches away from the Bootstrap 2 web framework to the next version, Bootstrap 3. This is in part because Bootstrap 2 is no longer being developed, and in part because it allows us to tap into the ecosystem of Bootstrap 3 themes.

  • In Bootstrap 3, images in <img> tags are no longer automatically scaled to the width of their container. If you use img() in your UI code, or <img> tags in your raw HTML source, it's possible that they will be too large in the new version of Shiny. To address this you can add the img-responsive class:
img(src = "picture.png", class = "img-responsive")

The R code above will generate the following HTML:

<img src="picture.png" class="img-responsive">
  • The sliders have been replaced. Previously, Shiny used the jslider library, but now it uses ion.RangeSlider. The new sliders have an updated appearance, and they have allowed us to fix many long-standing interface issues with the sliders.

  • The sliderInput() function no longer uses the format or locale options. Instead, you can use pre, post, and sep options to control the prefix, postfix, and thousands separator.

  • updateSliderInput() can now control the min, max, value, and step size of a slider. Previously, only the value could be controlled this way, and if you wanted to change other values, you needed to use Shiny's dynamic UI.
  • If in your HTML you are using custom CSS classes that are specific to Bootstrap, you may need to update them for Bootstrap 3. See the Bootstrap migration guide.

If you encounter other migration issues, please let us know on the shiny-discuss mailing list, or on the Shiny issue tracker.

If you would like to use Shiny 0.11 with Bootstrap 2, you can use the shinybootstrap2 package. Installation and usage instructions are on available on the project page. We recommend that you do this only as a temporary solution because future development on Shiny will use Bootstrap 3.

If you want to install a specific version of Shiny other than the latest CRAN release, you can use the install_version() function from devtools:

# Install devtools if you don't already have it:
# Install the last version of Shiny prior to 0.11
devtools::install_version("shiny", "")

Along with the release of Shiny 0.11, we've packaged up some Bootstrap 3 themes in the shinythemes package. This package makes it easy to use Bootstrap themes with Shiny.

  • Changed sliders from jquery-slider to ion.rangeSlider. These sliders have an improved appearance, support updating more properties from the server, and can be controlled with keyboard input.

  • Switched from Bootstrap 2 to Bootstrap 3. For most users, this will work seamlessly, but some users may need to use the shinybootstrap2 package for backward compatibility.

  • The UI of a Shiny app can now have a body tag. This is useful for CSS templates that use classes on the body tag.

  • actionButton and actionLink now pass their ... arguments to the underlying tag function. (#607)

  • Added observeEvent and eventReactive functions for clearer, more concise handling of actionButton, plot clicks, and other naturally-imperative inputs.

  • Errors that happen in reactives no longer prevent any remaining pending observers from executing. It is also now possible for users to control how errors are handled, with the 'shiny.observer.error' global option. (#603, #604)

  • Added an escape argument to renderDataTable() to escape the HTML entities in the data table for security reasons. This might break tables from previous versions of shiny that use raw HTML in the table content, and the old behavior can be brought back by escape = FALSE if you are aware of the security implications. (#627)

  • Changed the URI encoding/decoding functions internally to use encodeURI(), encodeURIComponent(), and decodeURIComponent() from the httpuv package instead of utils::URLencode() and utils::URLdecode(). (#630)

  • Shiny's web assets are now minified.

  • The default reactive domain is now available in event handler functions. (#669)

  • Password input fields can now be used, with passwordInput(). (#672)


  • Remove use of rstudio::viewer in a code example, for R CMD check.


  • Changed some examples to use \donttest instead of \dontrun.

shiny 0.10.2

  • The minimal version of R required for the shiny package is 3.0.0 now.

  • Shiny apps can now consist of a single file, app.R, instead of ui.R and server.R.

  • Upgraded DataTables from 1.9.4 to 1.10.2. This might be a breaking change if you have customized the DataTables options in your apps. (More info: https://github.com/rstudio/shiny/pull/558)

  • File uploading via fileInput() works for Internet Explorer 8 and 9 now. Note: IE8/9 do not support multiple files from a single file input. If you need to upload multiple files, you have to use one file input for each file.

  • Switched away from reference classes to R6.

  • Reactive log performance has been greatly improved.

  • Added Progress and withProgress, to display the progress of computation on the client browser.

  • Fixed #557: updateSelectizeInput(choices, server = TRUE) did not work when choices is a character vector.

  • Searching in DataTables is case-insensitive and the search strings are not treated as regular expressions by default now. If you want case-sensitive searching or regular expressions, you can use the configuration options search$caseInsensitive and search$regex, e.g. renderDataTable(..., options = list(search = list(caseInsensitve = FALSE, regex = TRUE))).

  • Added support for htmltools::htmlDependency's new attachment parameter to renderUI/uiOutput.

  • Exported createWebDependency. It takes an htmltools::htmlDependency object and makes it available over Shiny's built-in web server.

  • Custom output bindings can now render htmltools::htmlDependency objects at runtime using Shiny.renderDependencies().

  • Fixes to rounding behavior of sliderInput. (#301, #502)

  • Updated selectize.js to version 0.11.2. (#596)

  • Added position parameter to navbarPage.

shiny 0.10.1

  • Added Unicode support for Windows. Shiny apps running on Windows must use the UTF-8 encoding for ui.R and server.R (also the optional global.R) if they contain non-ASCII characters. See this article for details and examples: http://shiny.rstudio.com/gallery/unicode-characters.html (#516)

  • runGitHub() also allows the 'username/repo' syntax now, which is equivalent to runGitHub('repo', 'username'). (#427)

  • navbarPage() now accepts a windowTitle parameter to set the web browser page title to something other than the title displayed in the navbar.

  • Added an inline argument to textOutput(), imageOutput(), plotOutput(), and htmlOutput(). When inline = TRUE, these outputs will be put in span() instead of the default div(). This occurs automatically when these outputs are created via the inline expressions (e.g. r renderText(expr)) in R Markdown documents. See an R Markdown example at http://shiny.rstudio.com/gallery/inline-output.html (#512)

  • Added support for option groups in the select/selectize inputs. When the choices argument for selectInput()/selectizeInput() is a list of sub-lists and any sub-list is of length greater than 1, the HTML tag <optgroup> will be used. See an example at http://shiny.rstudio.com/gallery/option-groups-for-selectize-input.html (#542)

shiny 0.10.0

  • BREAKING CHANGE: By default, observers now terminate themselves if they were created during a session and that session ends. See ?domains for more details.

  • Shiny can now be used in R Markdown v2 documents, to create "Shiny Docs": reports and presentations that combine narrative, statically computed output, and fully dynamic inputs and outputs. For more info, including examples, see http://rmarkdown.rstudio.com/authoring_shiny.html.

  • The session object that can be passed into a server function (e.g. shinyServer(function(input, output, session) {...})) is now documented: see ?session.

  • Most inputs can now accept NULL label values to omit the label altogether.

  • New actionLink input control; like actionButton, but with the appearance of a normal link.

  • renderPlot now calls print on its result if it's visible (i.e. no more explicit print() required for ggplot2).

  • Introduced Shiny app objects (see ?shinyApp). These essentially replace the little-advertised ability for runApp to take a list(ui=..., server=...) as the first argument instead of a directory (though that ability remains for backward compatibility). Unlike those lists, Shiny app objects are tagged with class shiny.appobj so they can be run simply by printing them.

  • Added maskReactiveContext function. It blocks the current reactive context, to evaluate expressions that shouldn't use reactive sources directly. (This should not be commonly needed.)

  • Added flowLayout, splitLayout, and inputPanel functions for putting UI elements side by side. flowLayout lays out its children in a left-to-right, top-to-bottom arrangement. splitLayout evenly divides its horizontal space among its children (or unevenly divides if cellWidths argument is provided). inputPanel is like flowPanel, but with a light grey background, and is intended to be used to encapsulate small input controls wherever vertical space is at a premium.

  • Added serverInfo to obtain info about the Shiny Server if the app is served through it.

  • Added an inline argument (TRUE/FALSE) in checkboxGroupInput() and radioButtons() to allow the horizontal layout (inline = TRUE) of checkboxes or radio buttons. (Thanks, @saurfang, #481)

  • sliderInput and selectizeInput/selectInput now use a standard horizontal size instead of filling up all available horizontal space. Pass width="100%" explicitly for the old behavior.

  • Added the updateSelectizeInput() function to make it possible to process searching on the server side (i.e. using R), which can be much faster than the client side processing (i.e. using HTML and JavaScript). See the article at http://shiny.rstudio.com/articles/selectize.html for a detailed introduction.

  • Fixed a bug of renderDataTable() when the data object only has 1 row and 1 column. (Thanks, ZJ Dai, #429)

  • renderPrint gained a new argument 'width' to control the width of the text output, e.g. renderPrint({mtcars}, width = 40).

  • Fixed #220: the zip file for a directory created by some programs may not have the directory name as its first entry, in which case runUrl() can fail. (#220)

  • runGitHub() can also take a value of the form "username/repo" in its first argument, e.g. both runGitHub("shiny_example", "rstudio") and runGitHub("rstudio/shiny_example") are valid ways to run the GitHub repo.

shiny 0.9.1

  • Fixed warning 'Error in Context$new : could not find function "loadMethod"' that was happening to dependent packages on "R CMD check".

shiny 0.9.0

  • BREAKING CHANGE: Added a host parameter to runApp() and runExample(), which defaults to the shiny.host option if it is non-NULL, or "" otherwise. This means that by default, Shiny applications can only be accessed on the same machine from which they are served. To allow other clients to connect, as in previous versions of Shiny, use "" (or the IP address of one of your network interfaces, if you care to be explicit about it).

  • Added a new function selectizeInput() to use the JavaScript library selectize.js (https://github.com/brianreavis/selectize.js), which extends the basic select input in many aspects.

  • The selectInput() function also gained a new argument selectize = TRUE to makes use of selectize.js by default. If you want to revert back to the original select input, you have to call selectInput(..., selectize = FALSE).

  • Added Showcase mode, which displays the R code for an app right in the app itself. You can invoke Showcase mode by passing display.mode="showcase" to the runApp() function. Or, if an app is designed to run in Showcase mode by default, add a DESCRIPTION file in the app dir with Title, Author, and License fields; with "Type: Shiny"; and with "DisplayMode: Showcase".

  • Upgraded to Bootstrap 2.3.2 and jQuery 1.11.0.

  • Make tags$head() and singleton() behave correctly when used with renderUI() and uiOutput(). Previously, "hoisting content to the head" and "only rendering items a single time" were features that worked only when the page was initially loading, not in dynamic rendering.

  • Files are now sourced with the keep.source option, to help with debugging and profiling.

  • Support user-defined input parsers for data coming in from JavaScript using the parseShinyInput method.

  • Fixed the bug #299: renderDataTable() can deal with 0-row data frames now. (reported by Harlan Harris)

  • Added navbarPage() and navbarMenu() functions to create applications with multiple top level panels.

  • Added navlistPanel() function to create layouts with a bootstrap navlist on the left and tabPanels on the right

  • Added type parameter to tabsetPanel() to enable the use of pill style tabs in addition to the standard ones.

  • Added position paramter to tabsetPanel() to enable positioning of tabs above, below, left, or right of tab content.

  • Added fluidPage() and fixedPage() functions as well as related row and column layout functions for creating arbitrary bootstrap grid layouts.

  • Added hr() builder function for creating horizontal rules.

  • Automatically concatenate duplicate attributes in tag definitions

  • Added responsive parameter to page building functions for opting-out of bootstrap responsive css.

  • Added theme parameter to page building functions for specifying alternate bootstrap css styles.

  • Added icon() function for embedding icons from the font awesome icon library

  • Added makeReactiveBinding function to turn a "regular" variable into a reactive one (i.e. reading the variable makes the current reactive context dependent on it, and setting the variable is a source of reactivity).

  • Added a function withMathJax() to include the MathJax library in an app.

  • The argument selected in checkboxGroupInput(), selectInput(), and radioButtons() refers to the value(s) instead of the name(s) of the argument choices now. For example, the value of the selected argument in selectInput(..., choices = c('Label 1' = 'x1', 'Label 2' = 'x2'), selected = 'Label 2') must be updated to 'x2', although names/labels will be automatically converted to values internally for backward compatibility. The same change applies to updateCheckboxGroupInput(), updateSelectInput(), and updateRadioButtons() as well. (#340)

  • Now it is possible to only update the value of a checkbox group, select input, or radio buttons using the selected argument without providing the choices argument in updateCheckboxGroupInput(), updateSelectInput(), and updateRadioButtons(), respectively. (#340)

  • Added absolutePanel and fixedPanel functions for creating absolute- and fixed-position panels. They can be easily made user-draggable by specifying draggable = TRUE.

  • For the options argument of the function renderDataTable(), we can pass literal JavaScript code to the DataTables library via I(). This makes it possible to use any JavaScript object in the options, e.g. a JavaScript function (which is not supported in JSON). See ?renderDataTable for details and examples.

  • DataTables also works under IE8 now.

  • Fixed a bug in DataTables pagination when searching is turned on, which caused failures for matrices as well as empty rows when displaying data frames using renderDataTable().

  • The options argument in renderDataTable() can also take a function that returns a list. This makes it possible to use reactive values in the options. (#392)

  • renderDataTable() respects more DataTables options now: (1) either bPaginate = FALSE or iDisplayLength = -1 will disable pagination (i.e. all rows are returned from the data); besides, this means we can also use -1 in the length menu, e.g. aLengthMenu = list(c(10, 30, -1), list(10, 30, 'All')); (2) we can disable searching for individual columns through the bSearchable option, e.g. aoColumns = list(list(bSearchable = FALSE), list(bSearchable = TRUE),...) (the search box for the first column is hidden); (3) we can turn off searching entirely (for both global searching and individual columns) using the option bFilter = FALSE.

  • Added an argument callback in renderDataTable() so that a custom JavaScript function can be applied to the DataTable object. This makes it much easier to use DataTables plug-ins.

  • For numeric columns in a DataTable, the search boxes support lower and upper bounds now: a search query of the form "lower,upper" (without quotes) indicates the limits [lower, upper]. For a column X, this means the rows corresponding to X >= lower & X <= upper are returned. If we omit either the lower limit or the upper limit, only the other limit will be used, e.g. ",upper" means X <= upper.

  • updateNumericInput(value) tries to preserve numeric precision by avoiding scientific notation when possible, e.g. 102145 is no longer rounded to 1.0214e+05 = 102140. (Thanks, Martin Loos. #401)

  • sliderInput() no longer treats a label wrapped in HTML() as plain text, e.g. the label in sliderInput(..., label = HTML('A Label')) will not be escaped any more. (#119)

  • Fixed #306: the trailing slash in a path could fail addResourcePath() under Windows. (Thanks, ZJ Dai)

  • Dots are now legal characters for inputId/outputId. (Thanks, Kevin Lindquist. #358)

shiny 0.8.0

  • Debug hooks are registered on all user-provided functions and (reactive) expressions (e.g., in renderPlot()), which makes it possible to set breakpoints in these functions using the latest version of the RStudio IDE, and the RStudio visual debugging tools can be used to debug Shiny apps. Internally, the registration is done via installExprFunction(), which is a new function introduced in this version to replace exprToFunction() so that the registration can be automatically done.

  • Added a new function renderDataTable() to display tables using the JavaScript library DataTables. It includes basic features like pagination, searching (global search or search by individual columns), sorting (by single or multiple columns). All these features are implemented on the R side; for example, we can use R regular expressions for searching. Besides, it also uses the Bootstrap CSS style. See the full documentation and examples in the tutorial: http://rstudio.github.io/shiny/tutorial/#datatables

  • Added a new option shiny.error which can take a function as an error handler. It is called when an error occurs in an app (in user-provided code), e.g., after we set options(shiny.error = recover), we can enter a specified environment in the call stack to debug our code after an error occurs.

  • The argument launch.browser in runApp() can also be a function, which takes the URL of the shiny app as its input value.

  • runApp() uses a random port between 3000 and 8000 instead of 8100 now. It will try up to 20 ports in case certain ports are not available.

  • Fixed a bug for conditional panels: the value input.id in the condition was not correctly retrieved when the input widget had a type, such as numericInput(). (reported by Jason Bryer)

  • Fixed two bugs in plotOutput(); clickId and hoverId did not give correct coordinates in Firefox, or when the axis limits of the plot were changed. (reported by Chris Warth and Greg D)

  • The minimal required version for the httpuv package was increased to 1.2 (on CRAN now).

shiny 0.7.0

  • Stopped sending websocket subprotocol. This fixes a compatibility issue with Google Chrome 30.

  • The input and output objects are now also accessible via session$input and session$output.

  • Added click and hover events for static plots; see ?plotOutput for details.

  • Added optional logging of the execution states of a reactive program, and tools for visualizing the log data. To use, start a new R session and call options(shiny.reactlog=TRUE). Then launch a Shiny app and interact with it. Press Ctrl+F3 (or for Mac, Cmd+F3) in the browser to launch an interactive visualization of the reactivity that has occurred. See ?showReactLog for more information.

  • Added includeScript() and includeCSS() functions.

  • Reactive expressions now have class="reactive" attribute. Also added is.reactive() and is.reactivevalues() functions.

  • New stopApp() function, which stops an app and returns a value to the caller of runApp().

  • Added the shiny.usecairo option, which can be used to tell Shiny not to use Cairo for PNG output even when it is installed. (Defaults to TRUE.)

  • Speed increases for selectInput() and radioButtons(), and their corresponding updater functions, for when they have many options.

  • Added tagSetChildren() and tagAppendChildren() functions.

  • The HTTP request object that created the websocket is now accessible from the session object, as session$request. This is a Rook-like request environment that can be used to access HTTP headers, among other things. (Note: When running in a Shiny Server environment, the request will reflect the proxy HTTP request that was made from the Shiny Server process to the R process, not the request that was made from the web browser to Shiny Server.)

  • Fix getComputedStyle issue, for IE8 browser compatibility (#196). Note: Shiny Server is still required for IE8/9 compatibility.

  • Add shiny.sharedSecret option, to require the HTTP header Shiny-Shared-Secret to be set to the given value.

shiny 0.6.0

  • tabsetPanel() can be directed to start with a specific tab selected.

  • Fix bug where multiple file uploads with 3 or more files result in incorrect data.

  • Add withTags() function.

  • Add dateInput and dateRangeInput.

  • shinyServer() now takes an optional session argument, which is used for communication with the session object.

  • Add functions to update values of existing inputs on a page, instead of replacing them entirely.

  • Allow listening on domain sockets.

  • Added actionButton() to Shiny.

  • The server can now send custom JSON messages to the client. On the client side, functions can be registered to handle these messages.

  • Callbacks can be registered to be called at the end of a client session.

  • Add ability to set priority of observers and outputs. Each priority level gets its own queue.

  • Fix bug where the presence of a submit button would prevent sending of metadata until the button was clicked.

  • reactiveTimer() and invalidateLater() by default no longer invalidate reactive objects after the client session has closed.

  • Shiny apps can be run without a server.r and ui.r file.

shiny 0.5.0

  • Switch from websockets package for handling websocket connections to httpuv.

  • New method for detecting hidden output objects. Instead of checking that height and width are 0, it checks that the object or any ancestor in the DOM has style display:none.

  • Add clientData reactive values object, which carries information about the client. This includes the hidden status of output objects, height/width plot output objects, and the URL of the browser.

  • Add parseQueryString() function.

  • Add renderImage() function for sending arbitrary image files to the client, and its counterpart, imageOutput().

  • Add support for high-resolution (Retina) displays.

  • Fix bug #55, where renderTable() would throw error with an empty data frame.

shiny 0.4.1

  • Fix bug where width and height weren't passed along properly from reactivePlot to renderPlot.

  • Fix bug where infinite recursion would happen when reactivePlot was passed a function for width or height.

shiny 0.4.0

  • Added suspend/resume capability to observers.

  • Output objects are automatically suspended when they are hidden on the user's web browser.

  • runGist() accepts GitHub's new URL format, which includes the username.

  • reactive() and observe() now take expressions instead of functions.

  • reactiveText(), reactivePlot(), and so on, have been renamed to renderText(), renderPlot(), etc. They also now take expressions instead of functions.

  • Fixed a bug where empty values in a numericInput were sent to the R process as 0. They are now sent as NA.

shiny 0.3.1

  • Fix issue #91: bug where downloading files did not work.

  • Add [[<- operator for shinyoutput object, making it possible to assign values with output[['plot1']] <- ....

  • Reactive functions now preserve the visible/invisible state of their returned values.

shiny 0.3.0

  • Reactive functions are now evaluated lazily.

  • Add reactiveValues().

  • Using as.list() to convert a reactivevalues object (like input) to a list is deprecated. The new function reactiveValuesToList() should be used instead.

  • Add isolate(). This function is used for accessing reactive functions, without them invalidating their parent contexts.

  • Fix issue #58: bug where reactive functions are not re-run when all items in a checkboxGroup are unchecked.

  • Fix issue #71, where reactiveTable() would return blank if the first element of a data frame was NA.

  • In plotOutput, better validation for CSS units when specifying width and height.

  • reactivePrint() no longer displays invisible output.

  • reactiveText() no longer displays printed output, only the return value from a function.

  • The runGitHub() and runUrl() functions have been added, for running Shiny apps from GitHub repositories and zip/tar files at remote URLs.

  • Fix issue #64, where pressing Enter in a textbox would cause a form to submit.

shiny 0.2.4

  • runGist has been updated to use the new download URLs from https://gist.github.com.

  • Shiny now uses CairoPNG() for output, when the Cairo package is available. This provides better-looking output on Linux and Windows.

shiny 0.2.3

  • Ignore request variables for routing purposes

shiny 0.2.2

  • Fix CRAN warning (assigning to global environment)

shiny 0.2.1

  • [BREAKING] Modify API of downloadHandler: The content function now takes a file path, not writable connection, as an argument. This makes it much easier to work with APIs that only write to file paths, not connections.

shiny 0.2.0

  • Fix subtle name resolution bug--the usual symptom being S4 methods not being invoked correctly when called from inside of ui.R or server.R

shiny 0.1.14

  • Fix slider animator, which broke in 0.1.10

shiny 0.1.13

  • Fix temp file leak in reactivePlot

shiny 0.1.12

  • Fix problems with runGist on Windows

  • Add feature for on-the-fly file downloads (e.g. CSV data, PDFs)

  • Add CSS hooks for app-wide busy indicators

shiny 0.1.11

  • Fix input binding with IE8 on Shiny Server

  • Fix issue #41: reactiveTable should allow print options too

  • Allow dynamic sizing of reactivePlot (i.e. using a function instead of a fixed value)

shiny 0.1.10

  • Support more MIME types when serving out of www

  • Fix issue #35: Allow modification of untar args

  • headerPanel can take an explicit window title parameter

  • checkboxInput uses correct attribute checked instead of selected

  • Fix plot rendering with IE8 on Shiny Server

shiny 0.1.9

  • Much less flicker when updating plots

  • More customizable error display

  • Add includeText, includeHTML, and includeMarkdown functions for putting text, HTML, and Markdown content from external files in the application's UI.

shiny 0.1.8

  • Add runGist function for conveniently running a Shiny app that is published on gist.github.com.

  • Fix issue #27: Warnings cause reactive functions to stop executing.

  • The server.R and ui.R filenames are now case insensitive.

  • Add wellPanel function for creating inset areas on the page.

  • Add bootstrapPage function for creating new Bootstrap based layouts from scratch.

shiny 0.1.7

  • Fix issue #26: Shiny.OutputBindings not correctly exported.

  • Add repeatable function for making easily repeatable versions of random number generating functions.

  • Transcode JSON into UTF-8 (prevents non-ASCII reactivePrint values from causing errors on Windows).

shiny 0.1.6

  • Import package dependencies, instead of attaching them (with the exception of websockets, which doesn't currently work unless attached).

  • conditionalPanel was animated, now it is not.

  • bindAll was not correctly sending initial values to the server; fixed.

shiny 0.1.5

  • BREAKING CHANGE: JS APIs Shiny.bindInput and Shiny.bindOutput removed and replaced with Shiny.bindAll; Shiny.unbindInput and Shiny.unbindOutput removed and replaced with Shiny.unbindAll.

  • Add file upload support (currently only works with Chrome and Firefox). Use a normal HTML file input, or call the fileInput UI function.

  • Shiny.unbindOutputs did not work, now it does.

  • Generally improved robustness of dynamic input/output bindings.

  • Add conditionalPanel UI function to allow showing/hiding UI based on a JS expression; for example, whether an input is a particular value. Also works in raw HTML (add the data-display-if attribute to the element that should be shown/hidden).

  • htmlOutput (CSS class shiny-html-output) can contain inputs and outputs.

shiny 0.1.4

  • Allow Bootstrap tabsets to act as reactive inputs; their value indicates which tab is active

  • Upgrade to Bootstrap 2.1

  • Add checkboxGroupInput control, which presents a list of checkboxes and returns a vector of the selected values

  • Add addResourcePath, intended for reusable component authors to access CSS, JavaScript, image files, etc. from their package directories

  • Add Shiny.bindInputs(scope), .unbindInputs(scope), .bindOutputs(scope), and .unbindOutputs(scope) JS API calls to allow dynamic binding/unbinding of HTML elements

shiny 0.1.3

  • Introduce Shiny.inputBindings.register JS API and InputBinding class, for creating custom input controls

  • Add step parameter to numericInput

  • Read names of input using names(input)

  • Access snapshot of input as a list using as.list(input)

  • Fix issue #10: Plots in tabsets not rendered

shiny 0.1.2
