...osstype interaction,

I expect unequal sample sizes, so i have been trying to do it using Type III
sums-of-squares. Now, that's the model that i'm trying to run in R. My
attempts so far have looked like this:
>prod.anova <- aov(yproductivity ~
>foresttype+region+foresttype:region+crosstype+foresttype:crosstype+experiment+Error(linelabel),

After looking at the results of this model, my plan was to redo the model
with the foresttype:crosstype interaction as the Error() term, to get the
right F-test for &quo...

...vidual cross
only gives one value for a response variable, and has one state with respect
