Dear R users,
I have used the following model:
M1 <- gls(Nblad ~ Concentration+Season + Concentration:Season, data=DDD,
weights=varIdent(form=~ 1 | Season*Concentration))
to assess the effect of Concentration and Season on nitrogen uptake by
leaves (Nblad). I accounted for the difference in variance across the factor
levels by using the varIdent function.
Then I wanted to perform multiple
