I maintain a few internal R packages that we have at work. Recently, and perhaps foolishly, I decided that I needed to totally refactor one of them to add some more bells and whistles. A substantial part of this task involved simplifying the internal workflow of the package. I needed to be sure not to omit any of the previous functionality, but a simple list of all the exported and unexported functions was not sufficient.1
