[R-sig-ME] glmmadmb function

[Simona Picardi]

Dear members,

I'm using the glmmADMB package version 0.8.0 on R version 3.0.2 (2013-09-25) to run the following mixed effect models with gamma distribution:

mod1 <- glmmadmb(dist~test+(1|id),data=dataHS1,family="gamma")
mod2 <- glmmadmb(dist~test+(1|id),data=dataHS1,family="gamma",link="identity")

In the first case, using gamma with the default link, everything works fine.

As I try to specify link="identity", I get the following error message:

Error in glmmadmb(formula = dist ~ test + (1 | id), data = dataHS1, family = "gamma",  : 
  The function maximizer failed (couldn't find STD file) Troubleshooting steps include (1) run with 'save.dir' set and inspect output files; (2) change run parameters: see '?admbControl'
Inoltre: Warning message:
running command './glmmadmb -maxfn 500 -maxph 5 -noinit -shess' had status 21 
 Incompatible bounds in dvar_vector& dvar_vector::operator = (const dvar_vector& t)

I already tried to set the directory, but I keep getting the same error message. 

Any help would be hugely appreciated. 

Thanks in advance,
Simona Picardi
