[R] What happen for Negative binomial link in Lmer fonction?

[Emmanuelle Robardet]

Dear R users,
As I have no answer to my las reply i try again.
If the binomal negative link has never been implemented in the lmer
fonction, 
and as it was working when I did it some months ago,
What kind of result did I get?

This is the exemple of the answer of R when i was using lmer with negative
binomal family:

m1a<-lmer(atpos~ninter+saison+milieu*zone+(1|code),family=neg.bin(0.429),method="Laplace",data=manu)
summary(m1a)
Generalized linear mixed model fit using Laplace 
Formula: atpos ~ ninter + saison + milieu * zone + (1 | code) 
   Data: manu 
 Family: Negative Binomial(log link)
   AIC   BIC logLik deviance
 125.1 147.6 -54.57    109.1

Thank you for your answers,
Best Regards
Emmanuelle
