Dear S-plussers

I am doing kernel smoothening of presence-absence data of vascular
plants along a pH-gradient using FUN=ksmooth, kernel="triangle" and
bandwidth=1. I would like to know the neihgbourhood size used in the

I find it difficult to understand the short explanations about the
bandwidth parameter in the ksmooth function given in the manuals and
help menu. Can I infer the neighbourhood size from the bandwidth
