Dear Tom, As you can imagine, I watched your video with interest and found it quite impressive. I do have a couple of comments and a question.
The comments: You change a numeric ID variable into a factor with several thousand levels. I think that it would be more natural and efficient to assign the ID variable as the row names of the data set, which you can do via "Data -> Active data set -> Set case names". I also noticed that you run the Rcmdr from the RGUI MDI (multiple-document interface). This works better than it used to, but I think that it's still preferable to use the SDI (single-document interface). The question: You alluded repeatedly to the necessity to close the R graphics-device window after each plot in order "not to have the plots pile up on each other" (a paraphrase, but I think close to what you said). I'm not sure what you mean. In most cases, a new plot should just replace the previous one in the graphics-device window, unless you've turned plot recording on, in which case you should be able to page between plots. I've never had any trouble in either case, and am interested to learn what the problem is.
