r-lib/actions/setup-r@v1 is deprecated. Please update your workflow to use the 'v2' version. Also look at the examples at https://github.com/r-lib/actions/tree/v2/examples because '@v2' workflows are much simpler than 'v1' workflows.

The `set-output` command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/
