[R] Document Paths in R.app

I've been writing a package that allows a script to know its path, and I've
been struggling to get it working for 'R.app' on macOS.

For 'Rgui' on Windows, I used 'utils::getWindowsHandles' to get the
script's path

but it's only on Windows, and even if it wasn't, it seems like 'R.app' only
stores the basename in the window handle, so this won't work.

For 'RStudio', they provide a function from the environment 'tools:rstudio'
that retrieves the script's path, and it seems like there's an equivalent
environment 'tools:RGUI' (you can find the source code at this URL:
for 'R.app', but it claims to be for internal use only, and doesn't seem to
have a function for retrieving a document's path.

So my question, does anyone know of a way to retrieve the path of the
currently open document in 'R.app'? Thank you!
