[R] GLM quasipoisson error

[atorso at alumni.uv.es]

Hello,

I'm having an error when trying to fit the next GLM:

>>model<-glm(response ~ CLONE_M + CLONE_F + HATCHING
+(CLONE_M*CLONE_F) + (CLONE_M*HATCHING) + (CLONE_F*HATCHING) +
(CLONE_M*CLONE_F*HATCHING), family=quasipoisson)
>> anova(model, test="Chi")

>Error in if (dispersion == 1) Inf else object$df.residual : 
  missing value where TRUE/FALSE needed

If I fit the same model by using the Poisson distribution, it works.

I have not a clue about where the problem could be. Do you have any
idea or suggestion I could try?

Thank you in advance, 

Ana
