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

I had issues with the implementations above as my script is operated from a symlinked directory, or at least that's why I think the above solutions didn't work for me. Along the lines of @ennuikiller's answer, I wrapped my Rscript in bash. I set the path variable using pwd -P, which resolves symlinked directory structures. Then pass the path into the Rscript.

Bash.sh

#!/bin/bash

# set path variable
path=`pwd -P`

#Run Rscript with path argument
Rscript foo.R $path

foo.R

args <- commandArgs(trailingOnly=TRUE)
setwd(args[1])
source(other.R)
