[R] Manova and contrasts

[T.A.Wassenaar]

Hi,

In the archive I found a function for testing contrasts 
after manova, based on solving 'LBM=K'. There are a few 
questions on my mind:

1. A contrast between levels A and B of a certain factor 
with levels ABC is given as (0 -1 0) because the 
parameters for the intercept are fixed to zero in R. A 
contrast between B and C would then be (0 1 -1) right?

2. How would I go about if I want to determine which 
variate is causing rejection of the null hypothesis?

3. Is it also possible to construct confidence intervals 
for these contrasts?

Alternatively,

Does anyone by chance know whether it is possible to do 
multiple comparisons on multivariate data with the 
multcomp package? There seems to be an indication that it 
is possible, but I haven't been able to get it going.

Many thanks!
