Bryan, You might also wish to try the glmmPQL function in Venables and Ripley's MASS package. Someone reported success with it on the SIG-ECO R list nearly a year ago: https://stat.ethz.ch/pipermail/r-sig-ecology...

Pardon my exuberance, but this is simply awesome. What a treat to find on the front web page of the NY Times this morning under Technology. I think the article is very well written by the author, and I think...

Sorry for the delay in response. I had a somewhat similar need recently with the difference that I used a logit link for a bioassay. The design had different dose-response "replicates" that I modeled as "blocks". It looks like...
