Determine path of the executing script

Question

I have a script called foo.R that includes another script other.R, which is in the same directory:

#!/usr/bin/env Rscript
message(\         


        

Answer 1

This works for me. Just greps it out of the command line arguments, strips off the unwanted text, does a dirname and finally gets the full path from that:

args <- commandArgs(trailingOnly = F)  
scriptPath <- normalizePath(dirname(sub("^--file=", "", args[grep("^--file=", args)])))
