stepAIC/lme (1.6.2)

Based on the stepAIC help, I have assumed that it only was for lm, aov, and 
glm models. I gather from the following correspondence that it also works 
with lme models.

I am using windowsXP and have experimented with the data set HR from the 
SASmixed library without success with rw1.6.2.

I would greatly appreciate the correct syntax for version rw1.6.2.

Thank you very much,
