CONTRIBUTING

Please contribute!

We love collaboration.

If you do contribute...

Please follow these guidelines so that we can create good R packages that are easy to use and maintain. Forking and sending pull requests back to the master branch of this repo are best.

Guidelines for contribution

  • Documentation: All rOpenSci packages should use roxygen2 to document their functions. roxygen2 is an R package that automatically compiles your .Rd files in your man folder in your package if you write the documentation following certain rules. Check out Hadley's devtools wiki. It has some great advice for using roxygen2 to document R functions.

  • Vignettes: Contributing to vignettes is easy! We are moving towards writing all our vignettes in R Markdown, which is easy to write. These vignettes will be parsed to html on our web site. If you want to contribute to a vignette, make changes to the current .Rmd file in /inst/doc. If you want to add a new vignette, add a new file with a .Rmd extension in /inst/doc

  • Interacting with web based data: If you aren't familiar with working with web data in R, do get familiar with packages to make calls to web APIs, RCurl and httr, and to parse data once its in R, mainly RJSONIO/rjson/jsonlite and XML.

  • Do remember to track the upstream branch after you have forked this repo so that you can pull in any changes before you submit a pull request.

  • Contributing requires forking our repos to your Github account, making your changes, then submitting a pull request. Let us know if you aren't sure how to do this.

  • Does this package build after your changes? Test this by doing check(packagename) within R using devtools, or R CMD build path/to/package then R CMD CHECK packagename after. If the package does not build correctly, don't submit a pull request.

  • If you write a new function, try to write a test file for the function in the /inst/tests folder. Use functions from the test_that package to write tests, and see this wiki for help.

If you have any questions, get in touch: info@ropensci.org
