[R] Help with lme4 model specification

Thanks for your response.

Yes Spar_loc should look suspicious.  I posted the real error messages but
hid the variable names in the model.  Spar_loc is the original form of S.

This did not work.  However I did discover something that does:

AAT<- lmer(Y ~ S + A + (1|H %in% S:A), data=AT, REML=TRUE) 

Not sure why this worked.  I read that it is an alternate way of specifying
nesting.

This runs without error.
