Following lme model runs fine in general under R.2.1.1 but only for 9 out
of my 11 response variables under R.2.2.0.
model for one of my response variables:
Yresp is my response variable, F1fix is a fixed effect factor whereas
F2mix and F3mix are random effect factors.
const is set to rep(1,dim(Ycont)).
The strange thing is that if an intercept is omitted (F1fix-1) the R.2.2.0
also runs a 100 %. It's the same model, just with another
