Docker too unnecessarily complicated for our needs. Rather used renv as a way to pin and lock R and R package versions. This is a bit more natural to use than Docker (see conversation on R4DS):

Steps:

• Locally, ran renv::init(), then renv::snapshot() and then commit and push the created renv.lock file to github

• replaced current setup-r-dependencies line (which installs dependencies from the DESCRIPTION file) with setup-renv:

• uses: r-lib/actions/setup-renv@v2 with: cache-version: 2

  
  then added the rest of the github actions steps as per usual (environment variables etc too)
