On the boards for Ubuntu 8.10 64-bit, there were comments along the lines that:
/etc/X11/rgb.txt was missing. However, even after I replace this file, and logged back out in, this problem went away. It's shocking that a file as old/basic as /etc/X11/rgb.txt can be removed - I'm sure a lot of programs depend on it. -- View this message in context: http://www.nabble.com/-tcl--unknown-color-name-%22red%22-errors-tp22845915p22880689.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.
