multinomial logistic multilevel models in R

Question

Problem: I need to estimate a set of multinomial logistic multilevel models and can’t find an appropriate R package. What is the best R package to estimate such

Answer 1

Here's an implementation (not my own). I'd just work off this code. Plus, this way you'll really know what's going on under the hood.
