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,
