Probably. GPL and "non-commercial" are incompatible, so you can't distribute anything that mixes the two licenses. R itself has chosen to allow non-GPL packages, although there is a very fine line between a package as a "plug-in" vs. a "derived work". -- Peter Dalgaard Center for Statistics, Copenhagen Business School Solbjerg Plads 3, 2000 Frederiksberg, Denmark Phone: (+45)38153501 Email: pd....@cbs.dk Priv: pda...@gmail.com ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
