I looked at the Introduction to R and am still confused. Would it be possible to ask a question in which I have three vectors and I want to perform an anova on them. Say A,B, and C. Is there a standard form that I could use in lm to get a model that I could use in anova? Do I need to know more about my problem?
I really appreciate any help in this. anna On Monday 04 August 2003 03:26, Jim Lemon wrote: > Anna H. Pryor wrote: > > I am totally confused as to how to use anova.
