Trouble phrasing an R command that will run the model i need (ANOVA, nested)
...is an ANOVA with some crossed factors, interactions, and one
nested factor. I have listed them here:
(Factors "foresttype" through to "experiment" are all at the same level;
there is no nesting there, but the last factor listed is nested).
foresttype
region
foresttype:region
crosstype
foresttype:crosstype
experiment
linelabel (nested within every cell)
...and these are the appropriate F-test error terms:
foresttype -> tested against foresttype:crosstype interaction,
everything else -> tested against linelabel(nested)
I expect unequal sample sizes, so i have been trying...

I am trying to use multcomp to do a Tukey posthoc on growth increments among

...same set-up for them: each individual cross
only gives one value for a response variable, and has one state with respect
to each factor.
Just in the interests of clarifying things as much as possible: one of my
datasets looks like this(apologies if the formatting gets weird):
foresttype region crosstype experiment linelabel yproductivity
