Thanks for the reply. I change to another data set and the menu is available. I did not know the type of variable -- I am a newbie who is searching a quick solution, that's why I try R-commander. But after some test I find that plugin's output is not exactly what I want. I am seeking a way to visualize data by plotting grouped box and distribution chart. The latter may be called Q-Q chart, which I just learned from R, though it seems not exactly the same as I have seen below. I hope the groups are in the same chart for comparison, like this: http://cubeupload.com/im/WFc4CC.png or even plot a set of variables: http://cubeupload.com/im/wK69NN.jpg These charts are produced by Minitab. The norm-axis is not the same as Q-Q chart in R, but I think they are equivalent. Is it right? I hope you or the author of RcmdrPlugin.plotByGroup could implement the feature in the picture I posted. This "distribution chart" or Q-Q chart is the most I want from a statistic tool, since it gives full information of experiment data, and putting groups together in a chart for comparison is the ultimate judgement. Thank you for making R an easy tool to learn and use. Great job. -- 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.
