 This package is part of a richer suite called [fulltext](https://github.com/ropensci/fulltext), along with several other packages, that provides the ability to search for and retrieve full text of open access scholarly articles. We recommend using `fulltext` as the primary R interface to `rplos` unless your needs are limited to this single source.
