Hi Maarten,
I don't know how you are getting a plotting error from fitting a model?
But I suspect what you left out is that you did something like:
> M1<-gamm(call~s(signal variable), random=list(fanimal=~1), data=mydata,family=binomial)
> plot(M1)

and what you wanted is
> plot(M1$gam)

But with out more info that is the best I can do.

Nicholas
