re your second question, try the summary() and intervals() functions:

fm2 <- lme(distance ~ age + Sex, data = Orthodont, random = ~ 1)

## this might help you. have a look also at:



Hope this helps.

Subject: [R-sig-ME] SE of the mean in nlme

Folks; I'd like to know if there is anything similar to LSMEANS or MEANS 
from SAS PROC MIXED in nlme that would compare means of the fixed effects? 
Also, how do I get the SE of the mean (SEM) for fixed effects in nlme? 
Thanks a lot.
