Webbs is based on the function splineDesign . It generates a basis matrix for representing the family of piecewise polynomials with the specified interior knots and degree, evaluated at the values of x. A primary use is in modeling formulas to directly specify a piecewise polynomial term in a model. Webdegree of the piecewise polynomial—default is 3 for cubic splines. intercept: if TRUE, an intercept is included in the basis; default is FALSE. Boundary.knots: boundary points at which to anchor the B-spline basis (default the range of the non-NA data). If both knots and Boundary.knots are supplied, the basis parameters do not depend on x.
