Is anyone using the lmList() function in the lme4 package?
I use lmList() a fair bit because it is sort of a standard approach to data analysis in psychology when you can fit the model to each subject and then test the coefficients across subjects, or look at the correlations of the coefficients with something else. HOWEVER, for years before lme4 existed I was doing exactly the same thing with a loop. Thus, lmList() is merely a convenience for people like me. So the answer is that I WOULD BE HAPPY TO LIVE WITHOUT IT. Jon P.S. I hope that, eventually, lme4a works with languageR's pvals.fnc(). Right now it doesn't, and this is probably not your problem but theirs.
