getBbasis function

Description

A function returning the piecewise polynomial coefficients for a B-spline basis function i.e. the basis functions.

Usage

getBbasis(x, knots, degree, force = FALSE)

Arguments

x	a vector of data
knots	a vector of knots in ascending order. The first and last knots must be respectively the minimum and maximum of x.
degree	the degree of the spline
force	logical: skip check on knots? (not recommended!)

Value

the knots and the piecewise polynomial coefficients for a B-spline basis function i.e. the basis functions.
