Good point especially the reminder about the stringsAsFactors pitfall. The factor call to create my example was superfluous, but if I had included a character column the print method for dataframes would h=not have warned me anyway. Neither does the print method for data.tables. Only the print method for the dplyr-tibble objects gives a clear indication of factor-classed columns. -- Best; David Winsemius Alameda, CA, USA ______________________________________________ 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.
