Subject: [R] lme in R and Splus-7
Hi:
I used the function lme in R and Splus-7. With the same dataset and same
argument

Included below is some code to generate data and to fit a mixed effects
model to this fake data. The code works as expected when I call the
function lme in Splus but not in R.
The error message from calling lme in R is:
Error in getGroups.data.frame(dataMix, groups) :
