I have just started to work with S-plus, and have not yet understood how it
really works. I am now trying to fit a mixed effects model with lme. My goal
is to compare four different groups, at several different time points, and I
therefore would like to create confidence intervals for linear combinations
of my estimated parameters (as I usually do with "contrast" or "estimate" or
"lsmeans" in SAS). I have now found out that the vcov-function in the
lme4-package could be of great help for me, but I do not know if I can use
lme4 when working with S-PLUS 6.1, or is it only for R.
The lme4 package is only available for R at this time.
