Task view: Web Technologies and Services

Last updated on 2018-07-21 by Scott Chamberlain, Thomas Leeper, Patrick Mair, Karthik Ram, Christopher Gandrud

This Task View contains information about to use R and the world wide web together. The base version of R does not ship with many tools for interacting with the web. Thankfully, there are an increasingly large number of tools for interacting with the web. This task view focuses on packages for obtaining web-based data and information, frameworks for building web-based R applications, and online services that can be accessed from R. A list of available packages and functions is presented below, grouped by the type of activity. The Open Data Task View provides further discussion of online data sources that can be accessed from R.

If you have any comments or suggestions for additions or improvements for this Task View, go to GitHub and submit an issue, or make some changes and submit a pull request. If you can’t contribute on GitHub, send Scott an email. If you have an issue with one of the packages discussed below, please contact the maintainer of that package. If you know of a web service, API, data source, or other online resource that is not yet supported by an R package, consider adding it to the package development to do list on GitHub.

Tools for Working with the Web from R

Core Tools For HTTP Requests

There are two packages that should cover most use cases of interacting with the web from R. httr provides a user-friendly interface for executing HTTP methods (GET, POST, PUT, HEAD, DELETE, etc.) and provides support for modern web authentication protocols (OAuth 1.0, OAuth 2.0). HTTP status codes are helpful for debugging HTTP calls. httr makes this easier using, for example, stop_for_status(), which gets the http status code from a response object, and stops the function if the call was not successful. (See also warn_for_status().) Note that you can pass in additional libcurl options to the config parameter in http calls. curl is a lower-level package that provides a closer interface between R and the libcurl C library, but is less user-friendly. It may be useful for operations on web-based XML or to perform FTP operations. curl::curl() is an SSL-compatible replacement for base R’s url() and has support for http 2.0, SSL (https, ftps), gzip, deflate and more. For websites serving insecure HTTP (i.e. using the “http” not “https” prefix), most R functions can extract data directly, including read.table and read.csv; this also applies to functions in add-on packages such as jsonlite::fromJSON() and XML::parseXML. For more specific situations, the following resources may be useful:

  • RCurl is another low level client for libcurl. Of the two low-level curl clients, we recommend using curl. httpRequest is another low-level package for HTTP requests that implements the GET, POST and multipart POST verbs, but we do not recommend its use.
  • crul (GitHub) is an R6-based HTTP client that provides asynchronous HTTP requests, a pagination helper, HTTP mocking via webmockr, and request caching via vcr. It targets developers of other R packages more so than end users.
  • hrbrmstr/curlconverter (not on CRAN) is a useful package for converting curl command-line code, for example from a browser developer’s console, into R code.
  • request provides a high-level package that is useful for developing other API client packages. httping provides simplified tools to ping and time HTTP requests, around httr calls. httpcache provides a mechanism for caching HTTP requests.
  • For dynamically generated webpages (i.e., those requiring user interaction to display results), ropensci/RSelenium can be used to automate those interactions and extract page contents. It provides a set of bindings for the Selenium 2.0 webdriver using the JsonWireProtocol. It can also aid in automated application testing, load testing, and web scraping. seleniumPipes (GitHub) provides a “pipe”-oriented interface to the same. cpsievert/rdom (not on CRAN) uses phantomjs to access a webpage’s Document Object Model (DOM). hrbrmstr/decapitated provides headless Chrome browser orchestration.
  • For capturing static content of web pages postlightmercury is a client for the web service Mercury that turns web pages into structured and clean text.
  • Another, higher-level alternative package useful for webscraping is rvest, which is designed to work with magrittr to make it easy to express common web scraping tasks.
  • Many base R tools can be used to download web content, provided that the website does not use SSL (i.e., the URL does not have the “https” prefix). download.file() is a general purpose function that can be used to download a remote file. For SSL, the download() function in downloader wraps download.file(), and takes all the same arguments.
  • Tabular data sets (e.g., txt, csv, etc.) can be input using read.table(), read.csv(), and friends, again assuming that the files are not hosted via SSL. An alternative is to use httr::GET (or RCurl::getURL) to first read the file into R as a character vector before parsing with read.table(text=...), or you can download the file to a local directory. rio (GitHub) provides an import() function that can read a number of common data formats directly from an https:// URL. The repmis function source_data() can load and cache plain-text data from a URL (either http or https). That package also includes source_Dropbox() for downloading/caching plain-text data from non-public Dropbox folders and source_XlsxData() for downloading/caching Excel xlsx sheets.
  • Authentication: Using web resources can require authentication, either via API keys, OAuth, username:password combination, or via other means. Additionally, sometimes web resources that require authentication be in the header of an http call, which requires a little bit of extra work. API keys and username:password combos can be combined within a url for a call to a web resource (api key: http://api.foo.org/?key=yourkey; user/pass: http://username:[email protected]), or can be specified via commands in RCurl or httr. OAuth is the most complicated authentication process, and can be most easily done using httr. See the 6 demos within httr, three for OAuth 1.0 (linkedin, twitter, vimeo) and three for OAuth 2.0 (facebook, GitHub, google). ROAuth is a package that provides a separate R interface to OAuth. OAuth is easier to to do in httr, so start there. MarkEdmondson1234/googleAuthR provides an OAuth 2.0 setup specifically for Google web services.

Handling HTTP Errors/Codes

  • fauxpas brings a set of Ruby or Python like R6 classes for each individual HTTP status code, allowing simple and verbose messages, with a choice of using messages, warnings, or stops.
  • httpcode is a simple package to help a user/package find HTTP status codes and associated messages by name or number.

Parsing Structured Web Data

The vast majority of web-based data is structured as plain text, HTML, XML, or JSON (javascript object notation). Web service APIs increasingly rely on JSON, but XML is still prevalent in many applications. There are several packages for specifically working with these format. These functions can be used to interact directly with insecure webpages or can be used to parse locally stored or in-memory web files.

  • XML: There are two packages for working with XML: XML and xml2 (GitHub). Both support general XML (and HTML) parsing, including XPath queries. The package xml2 is less fully featured, but more user friendly with respect to memory management, classes (e.g., XML node vs. node set vs. document), and namespaces. Of the two, only the XML supports de novo creation of XML nodes and documents. The XML2R (GitHub) package is a collection of convenient functions for coercing XML into data frames. An alternative to XML is selectr, which parses CSS3 Selectors and translates them to XPath 1.0 expressions. XML package is often used for parsing xml and html, but selectr translates CSS selectors to XPath, so can use the CSS selectors instead of XPath.
  • HTML: All of the tools that work with XML also work for HTML, though HTML is - in practice - more prone to be malformed. Some tools are designed specifically to work with HTML. xml2::read_html() is a good first function to use for importing HTML. htmltools provides functions to create HTML elements. htmltab (GitHub) extracts structured information from HTML tables, similar to XML::readHTMLTable of the XML package, but automatically expands row and column spans in the header and body cells, and users are given more control over the identification of header and body rows which will end up in the R table. The selectorgadget browser extension can be used to identify page elements. RHTMLForms reads HTML documents and obtains a description of each of the forms it contains, along with the different elements and hidden fields. scrapeR provides additional tools for scraping data from HTML documents. htmltidy (GitHub) provides tools to “tidy” messy HTML documents. htm2txt uses regex to converts html documents to plain text by removing all html tags. Rcrawler does crawling and scraping of web pages.
  • JSON: There are several packages for reading and writing JSON: rjson, RJSONIO, and jsonlite. jsonlite includes a different parser from RJSONIO called yajl. We recommend using jsonlite. Check out the paper describing jsonlite by Jeroen Ooms https://arxiv.org/abs/1403.2805. jqr provides bindings for the fast JSON library, jq. jsonvalidate (GitHub) validates JSON against a schema using the “is-my-json-valid” Javascript library; validatejsonr does the same using the RapidJSON C++ library; ajv does the same using the ajv Javascript library. ndjson (GitHub) supports the “ndjson” format.
  • RSS/Atom: feedeR can be used to parse RSS or Atom feeds. tidyRSS parses RSS, Atom XML/JSON and geoRSS into a tidy data.frame.
  • swagger can be used to automatically generate functions for working with an web service API that provides documentation in Swagger.io format.

Tools for Working with URLs

  • The httr::parse_url() function can be used to extract portions of a URL. The RCurl::URLencode() and utils::URLencode() functions can be used to encode character strings for use in URLs. utils::URLdecode() decodes back to the original strings. urltools (GitHub) can also handle URL encoding, decoding, parsing, and parameter extraction.
  • The jayjacobs/tldextract package extracts top level domains and subdomains from a host name. It’s a port of a Python library of the same name.
  • iptools can facilitate working with IPv4 addresses, including for use in geolocation.
  • urlshorteneR offers URL expansion and analysis for Bit.ly, Goo.gl, and is.gd. longurl uses the longurl.org API to provide similar functionality.
  • gdns provides access to Google’s secure HTTP-based DNS resolution service.

Tools for Working with Scraped Webpage Contents

  • Several packages can be used for parsing HTML documents. boilerpipeR provides generic extraction of main text content from HTML files; removal of ads, sidebars and headers using the boilerpipe Java library. RTidyHTML interfaces to the libtidy library for correcting HTML documents that are not well-formed. This library corrects common errors in HTML documents. W3CMarkupValidator provides an R Interface to W3C Markup Validation Services for validating HTML documents.
  • For XML documents, the XMLSchema package provides facilities in R for reading XML schema documents and processing them to create definitions for R classes and functions for converting XML nodes to instances of those classes. It provides the framework for meta-computing with XML schema in R. xslt is an extension for the xml2 package to transform XML documents by applying an xslt style-sheet. (It can be seen as a modern replacement for Sxslt, which is an interface to Dan Veillard’s libxslt translator, and the SXalan package.) This may be useful for webscraping, as well as transforming XML markup into another human- or machine-readable format (e.g., HTML, JSON, plain text, etc.). SSOAP provides a client-side SOAP (Simple Object Access Protocol) mechanism. It aims to provide a high-level interface to invoke SOAP methods provided by a SOAP server. XMLRPC provides an implementation of XML-RPC, a relatively simple remote procedure call mechanism that uses HTTP and XML. This can be used for communicating between processes on a single machine or for accessing Web services from within R.
  • Rcompression (not on CRAN): Interface to zlib and bzip2 libraries for performing in-memory compression and decompression in R. This is useful when receiving or sending contents to remote servers, e.g. Web services, HTTP requests via RCurl.
  • tm.plugin.webmining: Extensible text retrieval framework for news feeds in XML (RSS, ATOM) and JSON formats. Currently, the following feeds are implemented: Google Blog Search, Google Finance, Google News, NYTimes Article Search, Reuters News Feed, Yahoo Finance and Yahoo Inplay.
  • webshot uses PhantomJS to provide screenshots of web pages without a browser. It can be useful for testing websites (such as Shiny applications).

Security

  • securitytxt identifies and parses web Ssecurity policy files.

Other Useful Packages and Functions

  • Javascript: V8 (GitHub) is an R interface to Google’s open source, high performance JavaScript engine. It can wrap Javascript libraries as well as NPM packages. The SpiderMonkey package provides another means of evaluating JavaScript code, creating JavaScript objects and calling JavaScript functions and methods from within R. This can work by embedding the JavaScript engine within an R session or by embedding R in an browser such as Firefox and being able to call R from JavaScript and call back to JavaScript from R. The js package wraps V8 and validates, reformats, optimizes and analyzes JavaScript code.
  • Email:: mailR is an interface to Apache Commons Email to send emails from within R. sendmailR provides a simple SMTP client. gmailr provides access the Google’s gmail.com RESTful API.
  • Mocking:: webmockr is a library for stubbing and setting expectations on HTTP requests. It is inspired from Rubys webmock. This package only helps mock HTTP requests, and returns nothing when requests match expectations. See Testing for mocking with returned responses.
  • Testing:: vcr provides an interface to easily cache HTTP requests in R package test suites (but can be used outside of testing use cases as well). vcr relies on webmockr to do the HTTP request mocking. httptest provides a framework for testing packages that communicate with HTTP APIs, offering tools for mocking APIs, for recording real API responses for use as mocks, and for making assertions about HTTP requests, all without requiring a live connection to the API server at runtime.
  • Miscellaneous: webutils contains various functions for developing web applications, including parsers for application/x-www-form-urlencoded as well as multipart/form-data. mime (GitHub) guesses the MIME type for a file from its extension. rsdmx provides tools to read data and metadata documents exchanged through the Statistical Data and Metadata Exchange (SDMX) framework. The package currently focuses on the SDMX XML standard format (SDMX-ML). robotstxt provides functions and classes for parsing robots.txt files and checking access permissions; spiderbar does the same. uaparserjs (GitHub) uses the javascript “ua-parser” library to parse User-Agent HTTP headers. rjsonapi consumes APIs that Follow the JSON API Specification. rapiclient is a client for consuming APIs that follow the Open API format. restfulr models a RESTful service as if it were a nested R list.
