Dear All
I wonder if anyone can help with this issue.?    I have two fixed factors (experimental group and sex) and a random factor (brood). I need the random factor to control for pseudoreplication because each brood provides a?    certain number of siblings, which are pseudoreplicates because share genes/environment. Then I have 8 variables. so I would like to to compare the covariance structures among groups while controlling for the random factor. I was told that R might do that, I mean a manova with mixed effects (manova(lme(....))?    

thanks for your help?    
David
