Thanks to Berwin for the very thorough explanation. At a more pragmatic level, I find that testdf$myfactor <- factor(testdf$myfactor,levels=unique(as.character(testdf$myfactor))) generally works OK to reorder the factor levels into the order in which they appear in the data set ... ______________________________________________ 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.
