[R-sig-ME] lme4 to MCMCglmm

Jarrod Hadfield (developer of MCMCglmm) has quite a bit of 
documentation, including an article at Journal of Statistical Software 
and fairly extensive course notes, included with the package.  Though, 
don't think of any that compares explicitly with lme4.

However, both packages can fit such a wide range of models, that I'm not 
sure whether "general" comparisons would be all that useful to you.

If you know what your model might be in (g)lmer, you might post that 
(ideally with real or fake data), and then I suspect you could get some 
more specific feedback about how to translate that into an MCMCglmm model.

cheers, Dave

Per a suggestion from David Atkins, I am trying to familiarize myself 
with the MCMCglmm package for the estimation of cross-classified 
mixed-effects models of inter-household food sharing.  I'm having a 
little trouble as I attempt to specify the model, however.

I am wondering if anyone knows of resources for folks who are working 
with MCMCglmm after already being familiar with lme4.  In other words, 
are there any online scripts or other resources from researchers who 
have first estimated models in lme4, then specified comparable models in
