[BioC] tukey test

[David martin]

Hi,
One quick question.

I have an expression data set mydata.eset.
I build up the design and contrast matrix as follows.


contrast.matrix <- design.pairs(c(group))  # design pairs is a quick 
function to do it automatically
fit2 <- contrasts.fit(fit, contrast.matrix)
fit2 <- eBayes(fit2)
results <- decideTests(fit2)

Ok so far so good, it works

Now i want to compute a tukyHSD test between the same groups.
It is not possible to use the fit object directly , how would you do 
that from your eset object and design matrix ??

thanks,
david
