This action checks an R package using the rcmdcheck package.

Inputs available:

• args - default c("--no-manual", "--as-cran"). Arguments to pass to the args parameter of rcmdcheck. It must be an R expression. Note that you often need to quote it, see details below.
• build_args - default "--no-manual". Arguments to pass to the build_args parameter of rcmdcheck. It must be an R expression. Note that you often need to quote it, see details below.
• check-dir - default "check". Arguments to pass to the check-dir parameter of rcmdcheck. It must be an R expression. Note that you often need to quote it, see details below.
• error-on - default "warning". Arguments to pass to the error-on parameter of rcmdcheck. It must be an R expression. Note that you often need to quote it, see details below.
• upload-snapshots - default false. Whether to upload all testthat snapshots as an artifact.
• upload-results - default false. Whether to upload check results for successful runs too.
• working-directory - default ".". If the R package to check is not in the root directory of your repository.
• artifact-name - Use this to override the default artifact name for the check results. The default is {os}-{arch}-r{rversion}-{id}-result, where {id} is matrix.config.id or strategy.job-index if the former is not defined.
• snapshot-artifact-name: Use this to override the default artifact name for testthat snapshots. The default is {os}-{arch}-r{rversion}-{id}-testthat-snapsots, where {id} is matrix.config.id or strategy.job-index if the former is not defined.

Basic:

steps:
- uses: actions/checkout@v4
- uses: r-lib/actions/setup-r@v2
- uses: r-lib/actions/setup-r-dependencies@v2
  with:
    extra-packages: any::rcmdcheck
    needs: check
- uses: r-lib/actions/check-r-package@v2

With specified inputs:

steps:
- uses: actions/checkout@v4
- uses: r-lib/actions/setup-r@v2
- uses: r-lib/actions/setup-r-dependencies@v2
  with:
    extra-packages: any::rcmdcheck
    needs: check
- uses: r-lib/actions/check-r-package@v2
  with:
    args: 'c("--no-manual", "--as-cran")'
    error-on: '"error"'
    check-dir: '"check"'

Several input arguments must be specified as an R expression. This increases flexibility, but it also causes some inconvenience, since these expressions often need to be quoted in the YAML file. A handy tip is that if your R expression does not contain a single quote, and you specify it in the YAML in a single line, surrounded by single quotes (like in the example above for args, error-on and check-dir right above), that will work.
