Hello R Folks, Would someone mind posting a simple example of a repeated measures analysis using lme? I''m trying to duplicate the analyses in Chapter 3 of the "SAS System for Mixed Models" manual, in particular those on p. 88-102 and involving different correlation structures. The data have the usual split-plot layout for repeated measures. I have downloaded the "SASMixed" examples from CRAN and run them, but except for the first example these don''t seem to match the SAS output. Thanks for any help. Best wishes, John Reeve

Did you look at Pinhiero and Bates (2000) Mixed Effects Models in S and S-Plus (Springer)? I''ve been able to do several things with lme using this book that I could not figure out without it; "lme" is state of the art but not easy to use. It is a space shuttle, not a bottle rocket.
