R help - Feb 2012 - B-spline/smooth.basis derivative matrices

Hello,
I've noticed that SPLUS seems to have a function for evaluating derivative
matrices of splines. I've found the R function that evaluates matrices from
'smooth.spline'; maybe someone has written something to do the same with
smooth.basis?
regards,
s

dear s,

If you are willing to use B-splines placing p knots, say, (rather than smoothing
splines
placing n knots), you could have a look to the functions splineDesign() or
spline.des()
(argument derivs) in the package "splines".
