[R-sig-ME] Anova/deviance table in glmmADMB

[John Fox]

Dear Thomas,

The Anova() function in the car package doesn't have a specific method for objects produced by glmmADMB() (with which I'm unfamiliar). If there are coef() and vcov() methods for those objects, then the default Anova() method should produce Wald tests.

Best,
 John
