Again, what I'm talking about: plotmeans is incapable of analyzing the formula. For example, I have two factors: A - a, b, c, and B - d, e, f.

If i plot: boxplot(num~A+B) what do I get? Eight boxes: ad, ae, af, ba, be, bf, cd, ce, cf. If I plot: plotmeans(num~A+B) - what do I get? Nothing. Because plotmeans cannot combine two factors in various combination. Is there a simple way to do it?

Anyway... That's wrong way, all what is neccessary is to have a boxplot with mean istead of median. Is there simple way to do it?

Statistical software like Statistica 7.0 offers any possible combination of what "Boxplot" could mean. Is it possible to have only one modification to R's boxplot?

Thank you for kind answers.

Also please tell me, where should I send replies: to conference adress
or to those who answer me directly.
