Hello Jim, Indeed, this might be the problem. When I try to install plyr, I get something like this: "Package xxx is not availlable (not for this version 3.0.x)" I was hoping that any old version from the Ubuntu repositories would be good enough for an absolute beginner. Thank you very much, Andreas ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
