Interface to the Search 'API' for 'PLoS' Journals

A programmatic interface to the 'SOLR' based search 'API' (< http://api.plos.org/>) provided by the Public Library of Science journals to search their articles. Functions are included for searching for articles, retrieving articles, making plots, doing 'faceted' searches, 'highlight' searches, and viewing results of 'highlighted' searches in a browser.

What is this?

rplos is a package for accessing full text articles from the Public Library of Science journals using their API.

Information

You used to need a key to use rplos - you no longer do as of 2015-01-13 (or v0.4.5.999).

PLoS API documentation here

Crossref API documentation here, and here. Note that we are working on a new package rcrossref (on CRAN) with a much fuller implementation of R functions for all Crossref endpoints.

Throttling

Beware, PLOS recently has started throttling requests. That is, they will give error messages like "(503) Service Unavailable - The server cannot process the request due to a high load", which means you've done too many requests in a certain time period. Here's what they say on the matter:

#> [1] "Mammalian females pay high energetic costs for reproduction, the greatest of which is imposed by lactation. The synthesis of milk requires, in part, the mobilization of bodily reserves to nourish developing young. Numerous hypotheses have been advanced to predict how mothers will differentially invest in sons and daughters, however few studies have addressed sex-biased milk synthesis. Here we leverage the dairy cow model to investigate such phenomena. Using 2.39 million lactation records from 1.49 million dairy cows, we demonstrate that the sex of the fetus influences the capacity of the mammary gland to synthesize milk during lactation. Cows favor daughters, producing significantly more milk for daughters than for sons across lactation. Using a sub-sample of this dataset (N = 113,750 subjects) we further demonstrate that the effects of fetal sex interact dynamically across parities, whereby the sex of the fetus being gestated can enhance or diminish the production of milk during an established lactation. Moreover the sex of the fetus gestated on the first parity has persistent consequences for milk synthesis on the subsequent parity. Specifically, gestation of a daughter on the first parity increases milk production by ∼445 kg over the first two lactations. Our results identify a dramatic and sustained programming of mammary function by offspring in utero. Nutritional and endocrine conditions in utero are known to have pronounced and long-term effects on progeny, but the ways in which the progeny has sustained physiological effects on the dam have received little attention to date."

Search within a field

There are a series of convience functions for searching within sections of articles.

  • plosauthor()
  • plosabstract()
  • plosfigtabcaps()
  • plostitle()
  • plossubject()

For example:

plossubject(q='marine ecology',  fl = c('id','journal'), limit = 10)
#> $meta
#> # A tibble: 1 x 2
#>   numFound start
#>      <int> <int>
#> 1     3560     0
#>
#> $data
#> # A tibble: 10 x 2
#>                                         id  journal
#>                                      <chr>    <chr>
#>  1            10.1371/journal.pone.0167252 PLOS ONE
#>  2      10.1371/journal.pone.0167252/title PLOS ONE
#>  3   10.1371/journal.pone.0167252/abstract PLOS ONE
#>  4 10.1371/journal.pone.0167252/references PLOS ONE
#>  5       10.1371/journal.pone.0167252/body PLOS ONE
#>  6            10.1371/journal.pone.0021810 PLoS ONE
#>  7      10.1371/journal.pone.0021810/title PLoS ONE
#>  8   10.1371/journal.pone.0021810/abstract PLoS ONE
#>  9 10.1371/journal.pone.0021810/references PLoS ONE
#> 10       10.1371/journal.pone.0021810/body PLoS ONE

However, you can always just do this in searchplos() like searchplos(q = "subject:science"). See also the fq parameter. The above convenience functions are simply wrappers around searchplos, so take all the same parameters.

BUG FIXES

  • Removed some examples from searchplos() that are now not working for some unknown reason. (#81)
  • Previously when user set limit=0, we still gave back data, this is fixed, and now the meta slot given back, and the data slot gives an NA (#85)

rplos 0.4.1

BUG FIXES

  • Fixed some broken tests.

rplos 0.4.0

NEW FEATURES

  • Errors from the data provider are reported now. At least we attempt to do so when they are given, for example if you specify asc or desc incorrectly with the sort parameter. See the check_response() function https://github.com/ropensci/rplos/blob/master/tests/testthat/test-check_response.R for examples.
  • New functions facetplos() and highplos() using the solr R wrapper to the Solr indexing engine. The PLOS API just exposes the Solr endpoints, so we can use the general Solr wrapper package solr to allow more flexible Solr searching.
  • New function highbrow() to visualize highlighting results in a browser.
  • New function plos_fulltext() to get full text xml of PLOS articles. Helper function full_text_urls() constructs the URL's for full text xml.

BUG FIXES

  • Fixed bug in tests where we forgot to give a key. No key is required per se, but PLOS encourages it so we prevent a call from happening without at least a dumby key.
  • Added function check_response() to check responses from the PLOS API, deals with capturing server error messages, and checking for correct content type, etc.

  • Removed function crossref_r() as we are working on a package for the CrossRef API.
  • Parameter arguments in searchplos(), plosauthor(), plosfigtabcaps(), plossubject(), and plostitle() were changed to match closer the Solr parameter names. terms to q. fields to fl. toquery to fq.
  • Multiple values passed to fields
  • returndf parameter is gone from searchplos(), plosauthor(), plosfigtabcaps(), plossubject(), and plostitle(). You can easily get raw JSON, etc. data using the solr package.
  • Now using httr instead of RCurl in plosviews() function.

rplos 0.3.6

NEW FEATURES

  • All search functions (searchplos(), plosabstract(), plosauthor(), plosfigtabcaps(), plossubject(), and plostitle()) gain highlighting argument, setting to TRUE (default=FALSE) returns matching sentence fragments that were matched. NOTE that if highlighting=TRUE the output can be a list of data.frame's if returndf=TRUE, with two named elements 'data' and 'highlighting', or a list of lists if returndf=FALSE.
  • All search functions (searchplos(), plosabstract(), plosauthor(), plosfigtabcaps(), plossubject(), and plostitle()) gain sort argument. You can pass a field to sort by even if you don't return that field in the output, e.g., sort='counter_total_month desc'.
  • A tiny function parsehighlight() added to parse out html code from highlighting output.

BUG FIXES

  • Some examples in docs didn't work - fixed them.
  • Fixed bug in searchplos() that was causing elements of a return field to cause failure because they were longer than 1 (e.g., authors). Now concatenating elements of length > 1.
  • Fixed bug in searchplos() that was causing elements of length 0 to cause failure. Now removing elements of length 0.
  • Fixed parsehighlight function to return NA if highlighting return of length 0.
  • Fixed broken test for plosauthor(), plosabstract(), and plot_throughtime().

rplos 0.3.0

NEW FEATURES

  • Added httr::stop_for_status() calls to a few functions to give informative http status errors when they happen

BUG FIXES

  • Fixed bug in plot_throughtime() that was throwing errors and preventing fxn from working, thanks to Ben Bolker for the fix.
  • Simplified code in many functions to have cleaner and simpler code.
  • ... parameter in many functions changed to callopts=list(), which passes in curl options to a call to either RCurl::getForm() or httr::GET()
  • Fixed bug in function plosviews() that caused errors in some calls. Now forces full document searches, so that you get views data back for full papers only, not sections of papers. See package alm (https://github.com/ropensci/alm) for more in depth PLOS article-level metrics.

rplos 0.2.0

NEW FEATURES

  • All functions for interacting with the PLOS ALM (altmetrics) API have been removed, and are now in a separate package called alm (http://github.com/ropensci/alm).
  • Convenience functions plosabstract, plosauthor, plosfigtabcaps, plossubject, and plostitle, that search specifically within those sections of papers now wrap searchplos, so they should behave the same way.
  • ldfast() fxn added as an attempt to do ldply faster
  • performance improvements in searchplos

BUG FIXES

  • Dependency on assertthat removed since it's not on CRAN.
  • Fixed namespace conflicts by importing only functions needed from some packages.
  • searchplos() now removes leading, trailing, and internal whitespace from character strings

rplos 0.1.1

  • remove alm*() functions so that this package now only wraps the PLoS search API.

rplos 0.1.0

  • The almdateupdated function has been deprecated - use almupdated instead.

  • The articlelength function has been deprecated - didn't see the usefulness any longer.

  • In general simplified and prettified code.

  • Changed from using RCurl to httr in many functions, but not all.

  • Added more examples for many functions.

  • Added three internal functions: concat_todf, addmissing, and getkey.

  • Added Karthik Ram as a package author.

BUG FIXES

  • All url arguments in functions put inside functions as they are not likely to change that often.

  • Fixed crossref function, and added more examples.

NEW FEATURES

  • The alm function (previously almplosallviews) gains many ### new features: now allows up to 50 DOIs per call; you can specify the source you want to get alm data from as an argument; you can specify the year you want to get alm data from as an argument.

  • Added the plosfields data file to get all the possible fields to use in function calls.

NEW FUNCTIONS

  • almplosallviews changed to alm.

  • almplotallviews changed to almplot.

  • almevents added to specifically search and get detailed events data for a specific source or N sources.

  • crossref_r gets 20 random DOIs from Crossref.org.

  • Added package startup message.

  • journalnamekey function to get the short name keys for each PLoS Journal.

rplos 0.0-7

IMPROVEMENTS AND ### BUG FIXES

  • ALM functions (any functions starting with alm) received updated arguments/parameters according to the ALM API version 3.0 changes.

  • ### Bug fixes in general across library.

  • Added tests.

  • almplosallviews now outputs different output - two data.frames, one total metrics (summed across time), and history (for metrics for each time period specified in the search)

  • crossref function returns R's native bibtype format. See examples in crossref function documentation

rplos 0.0-5

IMPROVEMENTS AND BUG FIXES

  • almpub changed to almdatepub

  • changed help file rplos to help - use help('rplos') in R

  • changed URL from http://ropensci.org/ to https://github.com/ropensci/rplos

  • added sleep argument to plosallviews function to allow pauses between API calls when running plosallviews in a loop - this is an attempt to limit hitting the PLoS API too hard

  • various other fixed to functions

  • more examples added to some functions

NEW FUNCTIONS

  • added function journalnamekey to get short keys for journals to use in searching for specific journals

rplos 0.0-1

NEW FEATURES

  • released to CRAN
