Hi all,

I am in a situation where I want to ask what is the effect of ecomorph,
diet, and family(nested in ecomorph) on a number of behaviours that are
repeated measures.  I use the Car package to run the MANOVA and it worked
on my previous data set.  However, on this new data set I get the
following error:

av.mod2<- anova(model2, idata=idata, idesign=~time)

Error in anova.mlm(object) : residuals have rank 70 < 72
In addition: Warning message:
In function (object, ..., test = c("Pillai", "Wilks", "Hotelling-Lawley",
 :
  models with response "NULL" removed because response differs from model
  1

I have a large number of behaviours included could this be the problem?

Does anyone have any idea what might be going on?
 
Allan
