rcrossref v0.8.4

NEW FEATURES

• The RStudio Addin now includes ability to search by article metadata, e.g., title (#148) (#152)
• you can now set a different base url for cr_cn() (#168)

MINOR IMPROVEMENTS

• better behavior for cr_cn() when bibentry not valid, that is not parseable. before the package we use to parse bibtex would stop on invalid bibentry data, but now we get around the invalid bits and give back the bibentry (#147)
• updated and improved documentation for filters (#161)
• improved description of the dois parameter (#162) thanks @ms609
• Much improved error behavior for cr_* functions. We now give errors like 404 (client error): /works/blblbl - Resource not found., which includes HTTP status code, major class of error (success, redirect, client, server), the route requested, and the error message (#163)

BUG FIXES

• fixed bug in cr_works() in which field queries should have been possible for title and affilitation, but were not. Fixed now. (#149)
• cr_journals() was not correctly parsing data when more than 1 ISSN given and works set to TRUE, fixed now (#156)
• cr_journals() was not correctly parsing data when no ISSN found and works set to TRUE, fixed now (#150)
• cr_journals() was not correctly handling queries with multiple ISSN's and works set to FALSE, fixed now (#151)
• fixed bug in cr_works(), and any other cr_* function that set works=TRUE. the license slot can have more than 1 result, and we were only giving the first back. fixed the parsing on this to give back all license results (#170)
