Hello everyone,
I am using the alpha version of glmmadmb, and it works for most of the time
except for one of my models. The weird thing is that it has worked before, a
couple of months ago, and for some reason it won't now and nothing has
changed.
The code is:
nbin5<-glmmadmb(stainp~beetle.ev+Caged*Section/SegmentT+(1|Site)+(1|Log.code),data=dat1,family="nbinom")
And it thinks for a while before giving me the error:
Error in glmmadmb(stainp ~ beetle.ev + Caged * Section/SegmentT + (1 | :
The function maximizer failed
In addition: Warning message:
running command './glmmadmb -maxfn 500' had status 1
I have narrowed it down, and the factor it has trouble with is "beetle.ev".
This is a column of binary data which is presence or absence of beetles.
There are only 0's and 1's in this column. The really weird thing is that I
have another column for a different beetle ("beetle"), binary also, which
works fine!
I have tried re-entering the data in another column, putting the "beetle.ev"
data in the "beetle" column, and nothing seems to work.
Any help would be much appreciated!
Thanks,
James

Sounds like you want to contact the author of the code rather than R-help. Uwe Ligges

Have you tried running it with verbose=TRUE ?

It is pretty much impossible that the same code worked before on
the same data and that truly *nothing* has changed. There must (?)
have been some minor change to the code or to the data,
even something apparently innocuous (and possibly a forehead-slapper
when you do figure out what it was).
This is not a reproducible example, so I can't really diagnose
it. Running with verbose=TRUE and posting the (voluminous) output
would help, but the best thing would be if you can post the data
somewhere, or a similar data set that displays the same problem.
glmmADMB is a somewhat special-purpose package (being built
on AD Model Builder); you might want to consider sending follow-ups
to the AD Model Builder mailing list.

Thanks for the reply Ben. I tried it with verbose=TRUE, and got about 7 pages of a word doc as an output, that ended with the error "Error in glmmadmb(stainp ~ beetle.ev + Caged * Section/SegmentT + (1 | : The function maximizer failed". I am not sure how I would best go about posting this, as you put it, "voluminous output", but I am happy to post/send that and a similar data-set somewhere. How would I best go about this?

Don't bother with the output, please send me the data and any accompanying R code (you can find my e-mail easily). Ben Bolker
