There is no base::errbar function. You probably were using a package and have not yet reinstalled that package under the new version of R. When I run sos::findFn('errbar') I see two packages (Hmisc and sfsmisc) with a function of that name. -- David Winsemius, MD Alameda, CA, USA ______________________________________________ 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.
