Peter,
I thought this one was noted and fixed, but I could be wrong.

It wasn't... However, all it needs is a bit of defensive programming. But should it (a) Protest if any(bin)>nbins or (b) Quietly set bin[bin>nbins] <- 0 # or NA, no matter (one could also start the routine with bin<-bin[bin<=nbin]) I think (b) since that is consistent with the way values <= 0 are currently handled.
