I had the same symptom a couple of days ago. It went away after quitting and restarting the R session. I kind of put it down to leaving an R session running while updating R (Yeah, I know: Still nothing reproducible...). The warning about nnet from 2.15.3 while installing to R-2.15.2/library suggests that something similar could be afoot in this case. -- Peter Dalgaard, Professor, 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.
