[R-sig-ME] error question

[Seth W. Bigelow]

This is a 'is the computer plugged in?' question, but...have you scrutinized
your input dataset to make sure all of your 'count' data are integers?

Hi everyone,

I am running Poisson mixed models in R and I get this error message:

Mensajes de aviso perdidos
In aic(y, n, mu, weights, dev) : non-integer x = 2.500000

Any clues on what it means and how to solve it???

Thanks
Alejandro
