This outlines how to propose a change to rgl. It is based on the corresponding document from the tidyverse project. For detailed info about contributing to tidyverse packages, please see the development contributing guide.
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. rgl puts help pages in .Rd files in the man directory (not in comments in the R source files, as many other projects do).
If you want to make a bigger change, it’s a good idea to first file an issue and make sure we agree 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).
Fork the package and clone onto your computer. If you haven’t done this before, we recommend using the Github web interface to fork, RStudio’s New Project... | Version Control | Git menu to import the repository. Then you can create branches locally, and push them to Github when you want to create a PR.
Install all development dependencies with devtools::install_deps(dependencies = TRUE), and then make sure the package passes R CMD check by running Build | Check. If R CMD check doesn’t pass cleanly, it’s a good idea to ask for help before continuing.
Make your changes, commit to git, push to Github, and then create a PR on the Github web page. The title of your PR should briefly describe the change. The body of your PR should contain Fixes #issue-number.
