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 tried almost everything from this question, Getting path of an R script, Get the path of current script, Find location of current .R file and R command for setting working directory to source file location in Rstudio, but at the end found myself manually browsing the CRAN table and found

scriptName library

which provides current_filename() function, which returns proper full path of the script when sourcing in RStudio and also when invoking via R or RScript executable.
