dbs generating derivative of given order of B-splines. It is a similar function with
splines::splineDesign. However, it provides a more user-friendly interface and more consistent handling on
deriv methods for derivatives of given order of any existing splines2 object that can be generated currently.
derivs to function
iSpline for derivatives.
Changed all the classes of object generated for a better dispatching on methods.
bSpline generating B-spline basis allowing zero degree or piecewise constant basis based on function
bs in package splines.
bSpline to allow M-splines of degree zero.
cSpline constructing convex spline (C-spline) basis.
predict methods for
bSpline2 object and
cSpline object generated by
iSplineto construct I-spline basis directly from B-spline basis instead of M-spline basis.
