expand.knots: Expands knots for appropriate number of knots in B-splines

In orthogonalsplinebasis: Orthogonal B-Spline Basis Functions

Expands knots for appropriate number of knots in B-splines

Description

This function is for convenience of specifying knots for B-splines. Since the user usually only want to specify the interval that they are interested in the end knots are usually duplicated. This function interprets the first and last knots as the end points and duplicates them.

Usage

expand.knots(interior, order = 4)

Arguments

interior	The knots including all interior and endpoint knots
order	the order of the splines that the knots are to be used with. Defaults to 4, being cubic splines

Value

A vector of knots with the order specified as an attribute
