An extra comment is that by suppressing the data -- ms(none)- -- you are losing much of the potential value of the plot. Regression people who leave the data off a scatter plot showing a regression line are usually regarded as missing the plot (so to speak). Why are ANOVA people allowed to get away with it?

Please remember to say, as requested in the FAQ, whenever you are using a user-written command and where it comes from. The error message indicates what the help for -anovaplot- explains: "With the second syntax [that used here: NJC], a varlist is supplied, which must be a permutation of the predictors previously used." So, the short answer is: Make sure your call to -anovaplot- is legal. I don't know, however, why you are using this second syntax at all. As your loop is over anova <something> exam_nb clinic a call to -anovaplot- without specifying any variables at all would seem to be what you want, i.e. -anovaplot-'s first syntax. Nick n.j.cox@durham.ac.uk Diego Bellavia I am trying to build a simple script to loop into some ANOVA for repeated measures tests and graph them with anovaplot. The script is the following: #delimit ; foreach X of varlist age blood_p cholesterol... {; anova `X' exam_nb clinic, repeated(exam_nb); anovaplot exam_nb, scatter(msym(none)); }; #delimit cr Where of course clinic is the ID of the subject, and exam_nb the ID of the single observation. When I run it as a command everything works fine but as soon as I put this in a .do file, I see the following message: "exam_nb not a permutation of exam_nb clinic" that makes sense to me but when I try to add clinic in the anovaplot command I get some weird graph I cannot understand... * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
