Hello<

I routinely use the following without a problem:

fm1<-lme(score~time,data,random=~time|ID)

tmp<-coef(fm1, augFrame=T)

However, in my current situation, I am running into the following error
when I execute the coef() call

Error in tapply(as.character(object[[nm]]), groups, FUN[[dClass]]) : 
        arguments must have same length

There are some cases with missing data, but I believe this was true in
prior successful attempts (although I do not recall exactly).

Any thoughts on this?

Thanks,

Harold
