[nlme] BLUPs for a new subject in a fitted lme model?

I am seeking for a method to calculate, given a fitted lme model and some data for a subject, the random effects predictors for this subject. I can only find predictors for the subjects used in creating the fit. Of course I could just add the subject and redo the fit. But I want to avoid just this refitting. Thanks for help wbk
Once you've a lme model, you don't need to stimate new random effects for new subjects. As stated by Pinheiro & Bates: "Fixed affects are parameters associated with an entire population, or with repeatable levels of experimental factors. Random effects are instead associated with experimental units drawn at random from a population." Maybe you'd like to see Pinheiro & Bates' book for further details.
