Is there a way to specify the col name "Y" to delete instead the

I have data (each Y_i is a vector) in the form of

Were it not for the measurement error (the epsilon_i) it's a very
simple model --- nice and balanced, compound symmetry, and I'd just
use lme(y ~ x1 + x2, random=~1|subj, ...) but the measurement
