GitHub actions for the R language

A collection of GitHub actions I've developed to enact continuous integration on my R packages.

These build on r-lib actions to facilitate some common tasks.

List of actions

1. ms609/actions/codemeta.R: Write package metadata to codemeta.js (superseded by update-codemeta).
2. ms609/actions/update-codemeta: Keep codemeta.json current from pull requests, without pushing to the default branch.
3. ms609/actions/pkgdown.R: Create package documentation website with pkgdown. Adapted from r-lib example.
4. ms609/actions/revdepcheck.R: Check reverse dependencies using r-lib/revdepcheck.
5. ms609/actions/validate-ctv.R: Ensure that CRAN task views are valid.
