Hello, I would like to run a model with nesting design in lmer but I always
got the error message "Matrices must have same number of columns in
rbind2(..1, r)". My model is:
 model_3R <-
lmer(N~Bareground+Habitat_type_simple+Presence+(1|Region/Ref_lmer),family =
"poisson")

of course it doesn't say you a lot, but maybe you know about this error
message. If I take the nested variable out, the model is running well. 
Thank you
