Contributing to chopin

Source: .github/CONTRIBUTING.md

This outlines how to propose a change to chopin.

Fixing typos

You can fix typos, spelling mistakes, or grammatical errors in the documentation directly using the GitHub web interface, as long as the changes are made in the source file. This generally means you’ll need to edit roxygen2 comments in an .R, not a .Rd file. You can find the .R file that generates the .Rd by reading the comment in the first line.

Bigger changes

If you want to make a bigger change, it’s a good idea to first file an issue and make sure someone from the team agrees that it’s needed. If you’ve found a bug, please file an issue that illustrates the bug with a minimal reprex (this will also help you write a unit test, if needed). See tidyverse team’s guide on how to create a great issue for more advice. When adding a new function to the package, always add working examples of the new function in roxygen2 documentation under #' @examples.

Pull request process

  • Fork the package and clone onto your computer. If you haven’t done this before, we recommend using usethis::create_from_github("NIEHS/chopin", fork = TRUE).

  • Install all development dependencies with devtools::install_dev_deps(), and then make sure the package passes R CMD check by running devtools::check(). If R CMD check doesn’t pass cleanly, it’s a good idea to ask for help before continuing.

  • Create a Git branch for your pull request (PR). We recommend using usethis::pr_init("brief-description-of-change").

  • Make your changes, commit to git, and then create a PR by running usethis::pr_push(), and following the prompts in your browser. The title of your PR should briefly describe the change. The body of your PR should contain Fixes #issue-number.

  • For user-facing changes, add a bullet to the top of NEWS.md (i.e. just below the first header).

Code style

  • Please abide by 80-character line rules (as default settings in lintr)

  • We use roxygen2, with Markdown syntax, for documentation.

  • We use testthat for unit tests. Contributions with test cases included are easier to accept.
