Dear Douglas,
"Noli illegitemes Carborundum!"
lme4 is a shining example of how statistical software should be developed with software, theory and practice all advancing together and in communication. I truly hope that this patch of nastiness, whatever it is, fades away and you get back on track. This is such a central part of statistics that the whole community is grateful for the time and efforts that you and your students have put into it. If others want to take a different approach they may surely develop their own software. I would be very sad if you took lme4 out of R. R does not belong to anyone, not even prominent members of the core group.
Best wishes, Murray Jorgensen
My thanks to you, Murray, and to the many other people who offered their support and encouragement privately. It is very gratifying to me to know that people appreciate access to the software and the discussions that we have been able to provide. In the last sentence I wrote "we" referring to the entire mailing list because the exchanges on the list and the suggestions from many people over the years have helped in the process of what Murray describes as "software, theory and practice all advancing together and in communication". For example, I have said on several occasions (but may never have written to this group) that the original suggestion to consider sparse matrix methods for mixed-effects or multilevel models came Harold Doran on the first day that I met him. He was attending a short course I was giving and, at a reception before the course, we were talking and he made this suggestion. Naturally my reaction was, "Hmm, that's interesting but I really don't know much about sparse matrix methods" and I planned to just go on with things as they had been. Fortunately, Harold is persuasive and convinced me that I should learn something about sparse matrices. Right now I plan to take a break from acrimonious discussions (and let me emphasize that it was not discussions on this list that made me so despondent - Murray's last sentence is much more to the point) and devote myself to developing code and writing a manuscript for a book. When the code is developed I will consider in more detail exactly how it should be released. For the time being I will retain the R-forge SVN archive. Again, let me say how much I appreciate the many kind messages I have received.

I regret that I have been absent from the list for some time. It happens that in the last couple of weeks I have been involved in a series of extremely unpleasant interactions on another, private email list that have left me with little enthusiasm for developing and supporting CRAN packages. One conclusion I have reached from these interactions is that I will never allow lme4 to be a recommended package in R. I am even having doubts about whether I want it to continue to be a CRAN package at all, as opposed to, say, moving it to Bioconductor or even switching development to another language. I'm sure the last option would be "cutting off my nose to spite my face" and I don't expect I would ever do that. There are many wonderful aspects to R and many reasons why I want to continue to use it. But right now I find myself forced to evaluate options other than putting a package on CRAN.
