validate.yaml

#' This example runs an R script that errors when there are problems with the 
#' data, causing the action to fail on GitHub.  It is set to run when changes 
#' are pushed to the main branch or when pull requests are made to the main 
#' branch, but *only* if the data/ folder has changes.  You can also run it with
#' a button on GitHub (`workflow_dispatch`).  Compared to the simple 
#' `hello_world.yaml` example, this handles installing R packages differently.  
#' The required packages are in a renv.lock file created by the `renv` R package.  
#' This workflow uses the setup-renv action to install those needed packages and 
#' cache them so this step runs faster subsequent times.  It also uses the `pak` 
#' package as a back-end to do the actual installing.  `pak` is able to deterine 
#' any system libraries or command line tools an R package needs and installs 
#' those as well.

  # push:
  #   branches: main
