For more detailed information about contributing to tidymodels packages, see our development contributing guide.


Typos or grammatical errors in documentation may be edited directly using the GitHub web interface, as long as the changes are made in the source file.

  • YES ✅: you edit a roxygen comment in an .R file in the R/ directory.
  • NO 🚫: you edit an .Rd file in the man/ directory.

We use roxygen2, with Markdown syntax, for documentation.


Before you submit 🎯 a pull request on a tidymodels package, always file an issue and confirm the tidymodels team agrees with your idea and is happy with your basic proposal.

  • For pull requests, we recommend that you create a fork of this repo with usethis::create_from_github(), and then initiate a new branch with usethis::pr_init().
  • Look at the build status before and after making changes. The README contains badges for any continuous integration services used by the package.
  • New code should follow the tidyverse style guide. You can use the styler package to apply these styles, but please don’t restyle code that has nothing to do with your PR.
  • For user-facing changes, add a bullet to the top of below the current development version header describing the changes made followed by your GitHub username, and links to relevant issue(s)/PR(s).
  • We use testthat. Contributions with test cases included are easier to accept.
