Fixing typos

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

  • YES: you edit a roxygen comment in a .R file below R/.
  • NO: you edit an .Rd file below man/.


Before you make a substantial pull request, you should always file an issue and make sure someone from the team agrees that it’s a problem. If you’ve found a bug, create an associated issue and illustrate the bug with a minimal reprex.

Pull request process

  • We recommend that you create a Git branch for each pull request (PR).
  • Look at the build status before and after making changes. The README should contain badges for any continuous integration services used by the package.
  • We recommend 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.
  • We use roxygen2.
  • We use testthat. Contributions with test cases included are easier to accept.
  • 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).
