While setting paths for caching dependencies it is important to give correct path depending on the hosted runner you are using or whether the action is running in a container job. Assigning different `path` for save and restore will result in cache miss.

Below are GiHub hosted runner specific paths one should take care of when writing a workflow which saves/restores caches across OS.

## R - renv
|

|

For renv, the cache directory will vary by OS. The `RENV_PATHS_ROOT` environment variable is used to set the cache location. Have a look at https://rstudio.github.io/renv/reference/paths.html#details for more details.
