[ADMB Users] glmmADMB error message

[Lisa Denmead]

Hi,

Sorry, no, this isn't the solution:

model2<-glmm.admb(aabundm2~babundm2+tramplingf*litterf,random=~1,group="block",
data=shit, family='nbinom')
Error in glmm.admb(aabundm2 ~ babundm2 + tramplingf * litterf, random = ~1,
:
  Argument "group" must be a character string specifying the name of the
grouping variable (also when "random" is missing)

I'm pretty sure I have the syntax right, as I have run the model in the way
I had it in the past and it has worked..

but thanks anyway!
