  ## <a id='vendoring'></a> Vendoring App Dependencies
  
  If you are deploying in an environment that is disconnected from the Internet, your application [must vendor its dependencies](https://github.com/cf-buildpacks/buildpack-packager/blob/master/doc/disconnected_environments.md).
  
  To set up your own custom, local CRAN-like repository to vendor your packages, create the `src/contrib` directories and populate them with your package source tarballs. For more information, check out this [step-by-step guide](https://rstudio.github.io/packrat/custom-repos.html).
  
  Add the `src/contrib` directories containing your package tarballs to a `vendor_r` directory at the root of your app. This directory is named as such so as not to conflict with vendor directories of other languages, such as python.
  
  Then, inside your `r.yml`, provide the names of your vendored packages in the `packages` list:
