More about this repository

For the most part, I try to follow the guidelines from R packages by Hadley Wickham. The unit tests are performed with testthat, the documentation is built with roxygen2, and the online package documentation is created with pkgdown. Continuous integration testing is performed for Linux by CircleCI, for macOS by Travis CI, and for Windows by AppVeyor. Code coverage is calculated with covr and Codecov.

The template files used by wflow_start() to populate a new project are defined in the list templates in the file R/infrastructure.R. The RStudio project template is configured by inst/rstudio/templates/project/wflow_start.dcf. The repository contains the files LICENSE and to both adhere to R package conventions for defining the license and also to make the license clear in a more conventional manner (suggestions for improvement welcome). document.R is a convenience script for regenerating the documentation. is a convenience script for running R CMD check. The remaining directories are standard for R packages as described in the manual Writing R Extensions.

Release checklist (for maintainers)

  • Bump version in DESCRIPTION,, and the test _workflowr.yml file
  • Update Check git log and make sure to reference GitHub Issues/PRs
  • Run document.R to update Rd files, install the package locally, and build the online documentation with pkgdown
  • Run to confirm tests pass locally
  • Test on rhub:
  • Test on winbuilder:
  • Update
  • Commit with git commit -am "Bump version: x.x.x.9xxx -> x.x.x and re-build docs."
  • Push with git push origin master and wait for CI builds to pass
  • Tag with git tag -a vx.x.x. Summarize entry into bullet points. Run git tag -l -n9 for past examples. Push with git push origin --tags.
  • Make a release. On GitHub, go to Releases -> Tags -> Edit release notes. Name the release “workflowr x.x.x” and copy-paste the Markdown entry from
  • Build tarball with R CMD build . and upload to CRAN submission site. You will receive an email to request confirmation, then an email confirming the package was submitted, and then an email with the test results. Once it is accepted to CRAN, monitor the check results for any surpise errors. Also, these builds are when the binaries are built for Windows and macOS, so they aren’t available until they are finished. You will receive an email once all the Windows binaries are available for download (devel, release, oldrel).
