I can't run the following code from "Mixed Effects Models in S and S-plus".
library( nlme )
options( width = 65, digits = 5 )
options( contrasts = c(unordered = "contr.helmert", ordered = "contr.poly")
# Chapter 5 Extending the Basic Linear Mixed-Effects Models
# 5.1 General Formulation of the Extended Model
data( Orthodont )
vf1Fixed <- varFixed( ~ age )
vf1Fixed <- initialize( vf1Fixed, data = Orthodont )
Can anyone help me?
