[R] ANOVA plotting

[Sarah Goslee]

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.
