Hi Pierre,

I'm having the same problem. I discovered a suggestion on another mailing list (stat.ethz.ch/mailman/listinfo/r-help) that using a delta argument would work ie pr1ML<-profile(fm1ML,delta=0.2). However, I have tried that and several smaller steps, but to no avail. 

I too am using lme4a and R-2.10.1 on windows 2007 professional.

Any help from anyone would be greatly appreciated.

>From the draft book on lme4: 
using lme4a, and the dyestuff data, I call profile and get: 

> profile(fm1ML) 

Error in UseMethod("profile") : 

no applicable method for 'profile' applied to an object of class 

any suggestions? 
using a R-2.10.1 on windows vista
