Hi
I suspect that what you want to do is to have a randon intercept for Rails. i.e.:
m<-lme(travel ~ Rail, data = Rail, random = ~ 1 | Rail)
You might want to try the documentation under C:\Program Files\R\rw1091\library\lme4\doc and also the book "Mixed-effect models in S and S-Plus" by Pinheiro and Bates.

Hi R-users:
I've got a problem with lme.
In Rail data,I try to model the next one
lme(travel ~ Rail, data = Rail, random = ~ Rail | Rail)
I want travel = Rail(i) + Rail(j) + epsilon(i,j)
say, an effect fixed for every Rail and other for Rail(j) random, R says fewer observations or false convergence.
Why can't I model an effect fixed and other random?
Thanks in advance.
