R does not store nor export the path of the currently running script. This is an attempt to circumvent this limitation by applying heuristics (such as call stack and argument inspection) that work in many cases. CAVEAT: Use this function only if your workflow does not permit other solution: if a script needs to know its location, it should be set outside the context of the script if possible.

This functions currently work only if the script was
or run with
Rscript or using the
--file parameter to the
R executable. For code run with
Rscript, the exact value
of the parameter passed to
Rscript is returned.
The path of the currently running script, NULL if it cannot be determined.
