[R-sig-ME] multiple errors when using glmmADMB

[Ben Bolker]

  The first thing that pops  out is the "non-integer response values in
discrete family" warning.  How are you measuring breeding success?  Can
you show us your whole glmmadmb() statement, and maybe a summary() of
the relevant columns of your data set?

   I'll also make the now-blanket statement that you may have better
luck moving forward with glmmTMB.

  cheers
