Hi,
I use anova() to find interaction effect and then I need to find data with
main effect from those data with interaction effect. How to do that?
I used : anova(lm(data~factor1*factor2)), then select data with interaction
effect. Then I need to select those data also with main effect of factor1
or factor2, from previous selected data. How to do that? Many thanks for
your time on my quesiton!
Fay
