Re: [R] lme intervals

          Have you tried "?intervals" and "?intervals.lme"? The following is an example under "?intervals.lme":

     fm1 <- lme(distance ~ age, Orthodont, random = ~ age | Subject)
      intervals(fm1)

Also, have you checked Pinheiro and Bates (2000) Mixed-Effects Models in S and S-Plus (Springer)? If this does not meet your needs and you don't find the answer in the documentation for predict.lme, please provide self-contained, toy example of what you want, as suggested in the posting guide! "www.R-project.org/posting-guide.html".

	  hope this helps.
