rplos 0.5.2

MINOR IMPROVEMENTS

• More tests added (#94)

BUG FIXES

• Fix encoding in parsing of XML data in plos_fulltext() to
  avoid unicode problems (#93)

rplos v0.5.0

MINOR IMPROVEMENTS

• Now importing non-Base R functions from utils, stats, and methods packages (#90)

BUG FIXES

• Fixes for httr v1 that broke rplos when length 0 list passed to query parameter (#89)

rplos 0.4.7

NEW FEATURES

• New function citations() for querying the PLOS Rich Citations API (#88)

BUG FIXES

• Added vignettes/figure to .Rbuildignore as requested by CRAN admin (#87)

v0.4.6

NEW FEATURES

• API key no longer required (#86)

MINOR IMPROVEMENTS

• searchplos() now returns a list of length two, meta and data, and meta is a data.frame of metadata for the search.
• Switched from CC0 to MIT license.
• No longer importing libraries RCurl, data.table, googleVis, assertthat, RJSONIO, and stringr (#79) (#82) (#84)
• Now importing dplyr.
• Moved jsonlite from Suggests to Imports. Replaces use of RJSONIO. (#80)
• crossref() now defunct. See package rcrossref https://github.com/ropensci/rcrossref. (#83)
• highplos() now uses solr::solr_highlight() to do highlight searches.
• searchplos(), plosabstract(), and other functions that wrap searchplos() now use ... to pass in curl options to httr::GET(). You'll now get an error on using callopts parameter.
• Added manual file entry for the dataset isocodes.
• Reworked both plosword() and plot_throughtime() to have far less code, uses httr now instead of RCurl, but to the user, everything should be the same.
• Made documentation more clear on discrepancy between PLOS website behavior and rplos behavior, and how to make them match, or match more closely (#76)
• Added package level man file to allow ?rplos to go to help page.

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)

v0.4.0

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 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.

IMPROVEMENTS

• 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.

v0.3.6

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().
