All Contributors Build Status

Check DOIs in a paper for being retracted by running your manuscript through retractcheck in R or using the Shiny app in your browser. This R package builds on the API of Open retractions (also an open source project).

The original inspiration for this package can be found [in a tweet by @PaolaPalma]( and the origin of the name in [this tweet by @MarkHoffarth]( :fire:

Retracted papers :books: keep getting cited (see for example here) and this package aims to help reduce this effect. Zotero provides retraction checking into your reference manager, so be sure to check that out too :+1:



Please note that the dependency on textreadr may fail if you don’t have the necessary software for that. If installation fails, try install.packages('textreadr') and see what errors it gives. It may look like this

Configuration failed because poppler-cpp was not found. Try installing:
 * deb: libpoppler-cpp-dev (Debian, Ubuntu, etc)
 * On Ubuntu 16.04 or 18.04 use this PPA:
    sudo add-apt-repository -y ppa:opencpu/poppler
    sudo apt-get update
    sudo sudo apt-get install -y libpoppler-cpp-dev
 * rpm: poppler-cpp-devel (Fedora, CentOS, RHEL)
 * csw: poppler_dev (Solaris)
 * brew: poppler (Mac OSX)


If the retractcheck package does not return any hits for retracted references, please note that the result is only as good as the data made available on this.
