thisfile: Determines the path of the currently running script

Description Usage Details Value Author(s) References See Also Examples

View source: R/thisfile.R

Description

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.

Details

This functions currently work only if the script was sourced, processed with knitr, 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.

Value

The path of the currently running script, NULL if it cannot be determined.
