R help - Oct 2008 - Fw: It 's correct to do contrasts for a GLM?

Hi all

I am one recent user of R and have a few doubts
I did a binomial GLM  with 3 - factor and now I have to test contrasts to 
identify that treatments are different. I know that the contrasts are used 
in ANOVA, it is not incorrect to use them in GLM? there is  a way  to do 
contrasts between treatments for GLM as a Tukey for the ANOVA?
