[R-sig-ME] Fwd: Multinomial response variable

  I think I replied privately that MCMCglmm can handle multinomial
models, and that library(sos); findFn("{multinomial mixed model}") finds
the mme package ...

  There are no immediate plans to make lme4 do multinomial models. It
can probably be done reasonably straightforwardly by decomposing the
problem into a series of parallel binomial models, but it's enough of a
nuisance and an effort to do it that it's pretty low on the development
list ...
