different DF in package nlme and lme4
...t; age 1 80 114.838 <.0001

---------------------------------------------------------------
Then I restarted!!! R to use the lme4 package instead of nlme.

library(lme4)
fm2b.1 <- lme(distance ~ age + Sex, data = Orthodont, random = ~ 1 | Subject)

augPred plot in nlme library
All,
I'm trying to create an augPred plot in the nlme library, similar to the
plot on
p.43 of Pinheiro & Bates (Mixed Effects Models in S and S-Plus) for
their Pixel data.
My data structure is the same as the example but I still get the error
msg below.
> comp.adj.UKV <- groupedData(adj.UKV ~ Time | Patient_no/Lisinopril,
data = comp.adj.UKV.frm, order.groups = F)
