Seems like vuong() doesn't work with objects of class glmmadmb, even if 
I compare negative binomial models only differing in zero inflation.

No, I'm running glmmadmb() with zeroInflation=TRUE

Ok, I need to change my strategy then. Probably I should look for a way 
to test for overdispersion in my data.

Thanks!
