[ADMB Users] Anova table for glmm.admb objects

Dear All,

I came across this posting (below) on a different list- how to get an Anova table from glmm.admb model objects- but I cannot get the car::Anova function to work for my model, or for the owl example I worked through from the glmmadmb package help notes, so I am guessing my code is wrong

When I tried it with the owl example I get the following message, the same as when I try for my model:

> car::Anova(fit_zipoiss)
Error in data.frame(df, teststat, p) :
  arguments imply differing number of rows: 5, 6
In addition: Warning message:
In Ops.factor(1, Nest) : | not meaningful for factors

(I am using glmm.admb v0.7.2.4)

Please could you advise, many thanks,
