ores can be obtained from CRAN with:

The package also lives on GitHub; you can install it with:




  • The 'reverted' function has been made defunct, following the decommissioning of that API endpoint.


  • Version 3.0 of the ORES API is now supported.


  • Support for the version 2 API is now included, fixing a bug in which NaNs were ommitted by the model-listing code at the API end
  • Article quality predictions are now available through check_quality()
