Hi Henrik,
Thanks for your feedback.
No matter what, I will implement suggestion #3 in the next version of COHCAP. I agree that is important.
Best,
Charles

Some quick ideas:
1. Before making the full call, call res <- system2(perlbin, "-v") to
assert no errors about running Perl itself. If an error, catch it and
given an information message ("Failed to run 'perl -v'" or something).
That will be user friendly as well for future users who run into
troubles.
2. Before calling system(), you can also assert that the script and
the input files are accessible, cf. file_test("-f") and file.access().
If not, give an informative error message.
3. Do res <- system(cmd, intern=TRUE, wait=TRUE) and report on 'res'
when there's an error. It will show the output of your Perl session.
4. You can use x <- normalizePath(x) to create OS-consistent paths/pathnames.
My $.02
