[R] SE estimates for treatment groups from nlme

Hi Katie,

maybe the easiest solution is to create a new factor that corresponds to
the combinations of the three factors A, B and C. A quick and dirty way
to create such a factor is:


ABC <- factor(paste(A, "x", B, "x", C, sep = ""))
ABC


and then fit the model using the variable ABC instead of A*B*C.
