- We recommend that you create a Git branch for each pull request (PR).
- We use roxygen2, with Markdown syntax, for documentation.
- We use testthat. Contributions with test cases included are easier to accept.
- For user-facing changes, add a bullet to the top of NEWS.md below the current development version header describing the changes made followed by your GitHub username, and links to relevant issue(s)/PR(s).
Before you make a substantial pull request, you should always file an issue and make sure someone from the developer team agrees that it’s a problem. If you’ve found a bug, create an associated issue and illustrate the bug.
As contributors and maintainers of this project, we pledge to respect all people who contribute through reporting issues, posting feature requests, updating documentation, submitting pull requests or patches, and other activities.
