Hello, I am using the glmmADMB package (I downloaded it using: install.packages("glmmADMB", repos="http://r-forge.r-project.org"), I am not sure which version it is). I'm on R version 2.15.1 GUI 1.52 Leopard build 64-bit, and yes, I'm on a mac.
I'm trying to run the following function: fit= glmmadmb(fruit ~ surroundings*town+(1|site), family='nbinom1', zeroInflation=TRUE)
and got the following error: dyld: unknown required load command 0x80000022Error in glmmadmb(fruit ~ surroundings * town + (1 | site), family = "nbinom1",  :   The function maximizer failed (couldn't find STD file)
My variables are fruit counts and there is overdispersion.
I added the zeroInflation because I read that it worked that way but in my case it still didn't. I also tried to download an older version of the package that I saw you recommended to someone. (I also tried with admb.opts=admbControl(shess=FALSE,noinit=FALSE)). Now I get the following error:Error in parse(text = lab) : object 'lab' not foundIn addition: Warning message:In is.na(rows) : is.na() applied to non-(list or vector) of type 'NULL'
I hope I have provided enough information and that my problem is clear enough...
Do you have any ideas that could help me resolve this problem? Or do you know of another package that would let me do a negative binomial with mixed factors? (I don't think the zero-inflated part is a problem).
Thank you very much,
