ANOVA plotting
I'm not sure what a "real ANOVA diagram" is supposed to look like, nor do I know what your data look like. But this might get you started: fakedata <- runif(100) fakegroups <- sample(rep(letters[1:5], each=20)) boxplot(fakedata ~ fakegroups) If that isn't what you're after, a clearer explanation with a reproducible example would help us help you.

Dear List, I recently started using R and I have a simple question. I am running R (v. 2.12.1) and Rcmdr (v.1-6.3) on Mac (Snow Leopard). I am using a data set I used before for practicing ANOVA with R, so I know what the results should look like. I can get ANOVA table using both Rcmdr and GUI. However, I cannot make R prepare the ANOVA diagram (with boxplots, showing the data points, including the outliers) for the dataset. If I use Rcmdr (Models>Graphs) then I get some graphical representation for the ANOVA model I prepared in R (showing diagnostic plots, Q-Q plots, etc.). However, the real ANOVA diagram is not coming up. I tried using "plot" command in GUI but did not get what I wanted. I could not find an answer to this on-line or in my book. I apologize if this was covered recently in the mailing list, I just became a member. Thanks for all the help!
