It seems I will use R often afterwards, so I will study the manuals and commands little by little. I do not reject the command line geek style, but the beginning steps and basic functions should be easy. Your Rcmdr offered this to new users; without it, I won't begin to learn and use R.
Your observations of my posted image are correct. So that is my expectation of grouped QQ plot. I hope it will come to Rcmdr soon. Also, thanks Google, I find a way to do that: http://www.sthda.com/english/wiki/ggplot2-qq-plot-quantile-quantile-graph-quick-start-guide-r-software-and-data-visualization That shape or color grouping in one chart is exactly what I need. Although I don't quite understand the commands used, I think I can copy and modify the commands a little to do my work. Could you incorporate it in the Rcmdr? Maybe consider it in your spare time. -- Best regards, Lu Wei PGP key ID: 0x A12F EF75 92CC E1EA ______________________________________________ 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.
