Multiple comparisons when interacction]
Hello,
I send the message again with the data file as txt because it seems not to
be accepted as csv in the R-help list.
Data comes from a multiyear field experiment in which 4 levels of a
treatment (2, 3, 4, 6) are compared to see the effect on yield. It is a
randomized complete block design.
The SAS code follows:
options ls=95;
data uno;
infile 'data.txt'

Multiple comparisons when interacction
In the model:
lm.1 <- lm(variable ~ BLOC + TIL * YEAR , data=selvanera)
I found TIL*YEAR interaction significant. Then I am trying to compare
means of the different levels of TIL inside every YEAR using:
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
