[R-sig-ME] Error with glmer when nesting students in school

[Christopher David Desjardins]

Unfortunately, that gives me a similar error.

 > glmer(sus ~ I(grade^2) + male*I(grade^2) + sped*I(grade^2) + 
ethnic*I(grade^2) + risk*I(grade^2) + (1+ I(grade^2) | schno.f/id.f), 
family=poisson, nAGQ=1, data= enroll.long.m)
Error in mer_finalize(ans) : q = 209642 > n = 175975

Cheers,
Chris
