In fact, I do not know if this is the best approach to analyze the data:
- Should block be considered as random? We use the same file and
randomization every year. We are interested in the long term effect of the

In the model:
lm.1 <- lm(variable ~ BLOC + TIL * YEAR , data=selvanera)

mc.2 <- glht(lm.1, linfct = mcp(TIL*YEAR="Tukey"))
summary(mc.2, test = univariate())
but it does not work.
There is any way of doing this, like the SLICE option in
