Multivariate Linear Mixed Model in lme4

Question

I wonder how to fit multivariate linear mixed model with lme4. I fitted univariate linear mixed models with the following code:

library(lme4)
lmer.m         


        

Answer 1

lmer and its elder sibling lme are inherently "one parameter left of ~". Have a look at the car packages; it offers no off-the shelf repeated measurement support, but you will find a few comments on the subject by searching the R list:
