perfect. I'd use predict.bSpline, it seems.
My problem was that I started looking in the wrong place. I was wandering
around the documentation on the web site, which I was unable to search
(pdf files). Now that I've installed R, and can search I see that R has
an enormous number of functions which will be useful to me. I didn't get
that impression from the 'Basics' book, though the book will be very
helpful as I get used to the data structures.
I think I'm going to like this language/package.
