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)
