I tried installing the source version of lme4, as you suggested, but still did not have success. I did get the following error message, however, so if the -3 version is significantly different than the -2 version I was able to install then it could still be an option. Warning: unable to access index for repository http://lme4.r-forge.r-project.org/repos/bin/windows/contrib/3.0 There is a binary version available (and will be installed) but the source version is later: binary source lme4 0.999999-2 0.99999911-3
I've added a more recent binary; it may take up to 24 hours for the r-forge repository to update. If you're in a big hurry you can download the zip file from https://r-forge.r-project.org/scm/viewvc.php/*checkout*/www/repos/bin/windows/ contrib/3.0/ lme4_0.99999911-3.zip?revision=1816&root=lme4 (URL broken to make Gmane happy, sorry) and install it using repos=NULL The differences you're seeing below wouldn't worry me *very* much -- the results are certainly qualitatively similar -- but it would be nice if the devel verion of lme4 happened to match HLM even more closely (it's not guaranteed of course that HLM is right and lme4 is wrong, but HLM has probably still been more thoroughly tested ...)
