[R-sig-ME] Nested fixed factors in glmer: Error in mer_finalize(ans) : Downdated X'X is not positive definite, 1.

[PALACIO BLASCO, SARA]

Dear All,

Maybe this is a trivial question but: how can I specify a nested  
structured of fixed factors in glmer?

I still haven't found a way to solve the issues explained in my  
previous e-mail.

Thanks for your help,

Sara Palacio
