rprojroot

This package helps accessing files relative to a project root to stop the working directory insanity. It is a low-level helper package for the here package.

Example

The rprojroot package works best when you have a “project”: all related files contained in a subdirectory that can be categorized using a strict criterion. Let’s create a package for demonstration.

R packages satisfy the is_r_package criterion. A criterion is an object that contains a find_file() function. With pkg as working directory, the function works like file.path(), rooted at the working directory:

This works identically when starting from a subdirectory:

There is one exception: if the first component passed to find_file() is already an absolute path. This allows safely applying this function to paths that may be absolute or relative:

As long as you are sure that your working directory is somewhere inside your project, you can retrieve the project root.

Installation and further reading
