Subject: [R] Obtaining Least Square Means with lme (mixed models)

Hi Dear Alex, A few years ago you sent this email to R list:

Hello,
I was wondering how one could obtain LSM for fixed factors in a
mixed-effect model using lme. In other words, if I have model such as:
model<-lme(yield~period+treatment+period*treatment,
data=data,random=~1|cow)
how can I get LSM for period, treatment and their interaction?
Thanks a lot!
Alex

What was the response?? I have the same question!

Thanks!
