[ADMB Users] glmmADMB-Function maximizer failed Poisson, ZIPoisson, NB1, ZINB1

[Ben Bolker]

  If you get the very latest version of glmmADMB (i.e. re-install from
r-forge)  you should be able to do the following:


step 1

glmmadmb(...,admb.opts=admbControl(run=FALSE),debug=TRUE,save.dir="glmmtmp")

  This should set up a temporary 'glmmtmp' directory (or whatever you
want to call it), copy the glmmadmb binary over to that directory (if
necessary -- this only happens on MacOS and Linux, not on Windows), and
create the glmmadmb.dat and glmmadmb.pin input files.  It should also
generate output that tells you what command would be run by glmmADMB to
run the model.

step 2

  change to the temporary directory and run the command (which in your
case would be

C:\WINDOWS\system32\cmd.exe /c "C:/Program
Files/R/R-2.14.0/library/glmmADMB/bin/windows32/glmmadmb.exe" -maxfn 500
-noinit

 step 3 (optional) if you successfully run the glmmadmb binary outside
of R and then want to import the information back into R, you can run
the code from step 1 again within R; this time it will find the output
files that have been created.

  Let me know how it goes.
