<p>In <a href="https://stats.stackexchange.com/questions/32994/lme4-vs-mcmcglmm-what-are-r-structure-g-structure-in-a-glmm">my question</a>, I had an answer that wasn't understandable (for me) but in the comments to that answer and also the comments to the original question, I got some very useful info, although it made me more confused ! So now I think the way forward is to post a reproducible example with <code>lme4</code> (<code>glmer()</code>) and <code>MCMCglmm()</code> operating on the same data and ask about the differences in the results (specifically about the R-structure). I have now made a reproducible example. So should I amend the question (which will make many of the comments redundant, but possibly not the one answer) or should I ask a new question ?</p>
