this.proj: Construct Path to File, Beginning with Your Project Directory
Description
this.proj behaves very similarly to here::here except that you
can have multiple projects in use at once, and it will choose which project
directory is appropriate based on this.dir(). Arguably, this
makes it better than here::here.
Usage
this.proj(...)
Value
A character vector of the arguments concatenated term-by-term, beginning with
the project directory.
