Thanks, I had indeed several versions of R and removed the older ones and it worked.
I suspect you have more than one version of R installed and are mixing them up. Those symbols have been in package stats for quite a while. Try starting R with --vanilla, and if that works, clean out your startup files (see ?Startup). If not, remove all your R installations and reinstall R 2.7.0 (or R-patched). -- View this message in context: http://www.nabble.com/unable-to-use-functions-require-DLL-from-package-%22base%22-tp17086783p17101073.html Sent from the R help mailing list archive at Nabble.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.
