Has anyone performed a multivariate mixed model with lme or lmer?  An
example of such a model is in Fieuws & Verbeke (2004), "Joint modelling of
multivariate longitudinal profiles, pitfalls of the random effects
approach," Statistics in Medicine, 23:3093-3104.  They also developed a
pairwise fitting method for the case when the number of response variable is
large (Biometrics 2006; 62:424-431), and the implementation was done in SAS.
In any event, I'd rather avoid SAS and do my analysis in R and was wondering
if anyone here could provide any pointers.  Not much turned up in the
archives on this.
