Cubic Smoothing Splines

[Michel Friesenhahn <michel.friesenhahn.b@bayer.com>]

I'm fitting cubic smoothing splines with smooth.spline().  Does anybody know how
to get the cubic polynomial coefficients for each of the knots?  I've used
looked at the $fit$coef component for the output of predict() but can't make
sense of it.

Thanks in advance for any help!
