[R] setting the current working directory to the location of the source file

AFAIK a script run through source() does not have any legit way to learn about it's own location.

I need this to make sure that the script will find its datafiles after I move the whole directory. (The datafiles are in the same directory.)

Here is a hack I invented to work around it:

print(getwd())
source_pathname = get("ofile",envir = parent.frame()) source_dirname = dirname(source_pathname ) setwd(source_dirname)
print(getwd())

Question: Is there a better, cleaner way?

Thanks,
mrgomel
