1. Fork the repo and clone the repo to local.
2. Remove all existing tests and GitHub Action workflows.
3. Add Yihui's example as a test. Wrap the last step n - 454 in an expect_indetical() call and set the comparison to condition to 0.
4. Run rhub::rhub_setup() to add the R-hub v2 workflow.
5. Add, commit, and push the above changes.
6. Run rhub::rhub_check() to run R-hub checks and select options to run the workflow. You might be prompted to set up a GitHub PAT locally and need to do that.
