[ADMB Users] error message for glmm.admb

[Tom Snijders]

Hi,

I got an error message when using gllmADMB under R 2.12.0. I solved it myself, but you might want to know about it.

Using R 2.12.0, I had just installed glmmADMB version 0.4-2 from R-Forge.
When running the function

(fm <- glmm.admb(y~Base*trt+Age+Visit, random=~Visit, group="subject",
                  data=epil2, family="nbinom"))

I got the error message

"'.exe' is not recognized as an internal or external command"
etcetera.

Inspired by the answer given by Dave Fournier (aug 30, 2010) that I found on
http://groups.google.com/group/admb-users/browse_thread/thread/3290046d9a63be70
I did a bit of hacking on glmm.admb.
It turns out that the command
cmd <- paste("\"", system.file("bin", "windows", file_name,
            package = "glmmADMB"), ".exe", "\"", " ", cmdoptions,
            sep = "")
is not working properly on my installation.
When I change it to

cmd <- paste("C:/R/R-2.12.0/library/glmmADMB/bin/windows/nbmm.exe \ ",cmdoptions,sep="")

(which is the file path and name on my installation), all works fine.
So it seems that the system.file()  function does not work as you expect it to.
I know too little of R to easily see what is going wrong there.

Good luck, cheers to you,
