Dear R Users,

I receive an error message when using the dredge function in MuMIn on a glmer.nb glmerMod object.

"Error in dredge(cm.nb) :
  call to 'global.model' contains '...' arguments and cannot be updated: glmer(formula = CM ~ BUSH + FRAG + I(TREE^2) + (DWELL * TREE) + (1 | XSCAPE), data = ..2, family = negative.binomial(theta = th))"

Before I provide an example I thought it best to ask: is it possible to dredge a glmer.nb glmerMod object?

I have successfully dredged other glmerMod objects as well as negative binomial mixed model objects from glmmadmb.

Any pointers would be much appreciated as the fitted vs residual plots from glmer.nb are much less skewed than those from glmmadmb.

Best wishes,
Fiona
