[R-sig-ME] gamm

[Maarten de Groot]

Dear list,

I would like to relate probability of responding animals to a signal 
variable. because the relationship is not linear, I used gam with 
binomial distribution. Till here there was no problem. However, the 
animals were used repeatedly for different values of the signal 
variable, I included the animal as a random factor (N = 26). Furthermore 
I have missing values, because some animals died during the process. 
When running the following model: M1<-gamm(call~s(signal variable), 
random=list(fanimal=~1), data=mydata,family=binomial), I encountered the 
following message:

Error in plot.window(...) : need finite 'xlim' values
In addition: Warning messages:
1: In min(x) : no non-missing arguments to min; returning Inf
2: In max(x) : no non-missing arguments to max; returning -Inf
3: In min(x) : no non-missing arguments to min; returning Inf
4: In max(x) : no non-missing arguments to max; returning -Inf

Can someone help what went wrong and give some advise on letting the 
model run correctly.

Kind regards,

Maarten de Groot
