hoardr introduction

hoardr is a package for managing cached files.

The benefit of using hoardr vs. raw rapddirs is that hoardr exposes an easy to use R6 class that has variables and functions within it, so you don’t have to import function foo or bar, etc. Just a single object.

You can easily wrap hoardr with user facing functions in your own package to manage cached files.

If you find any bugs or have any feature requests get in touch at https://github.com/ropensci/hoardr.
