Hi everybody

I want to specify the contrasts to build a cell means model on LME when 
there are several fixed effect  as factors in the model and also 
interactions between them.  Can anybody give me a hint on how to do 
accomplish this? How can I override the default "Contr.Treatment" for linear 
models?  I tried removing the intercept but this will only give me the mean 
values just for the first factor included in the model but then will use 
"contrast treatment" for all the other factors.

Thanks for your help!

Francisco
