Torsten, your message is a bit terse. Do you have Omegahat's RSPerl package installed? If not, visit www.omegahat.org, and have a look at the documentation. (Btw, you will find a lot of other useful stuff there.)
Sorry that I can't offer more at the moment -- but to know where to start may be better than nothing ;-) Cheers, Jörg ______________________________________________ R-help@stat.math.ethz.ch 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.
