lpc.splinefun: Auxiliary functions for spline fitting and projection.

In LPCM: Local Principal Curve Methods

Auxiliary functions for spline fitting and projection.

Description

Internal functions of package LPCM called by lpc.spline and others. These will rarely be called directly by the user.

Usage

lpc.splinefun(lpcobject)

lpc.fit.spline(lpcsl, num.knots = 100)

lpc.spline.eval(lpcsl, or.pi, branch = 0)

lpc.project.spline(lpcsl, newdata, num.knots = 100, optimize = TRUE)

lpc.curve.length(lpcsl, or.pi, branch = 0, total.subdivisions = 10000,
      min.subdivisions = 100)

Arguments

lpcobject	Object of type lpc.
lpcsl	Object generated by lpc.splinefun.
num.knots	number of spline knots
or.pi	original projection index
branch	branch ID
newdata	new data frame
optimize	Boolean.
total.subdivisions	total number of subdivisions for arc length computation.
min.subdivisions	minimum number of subdivisions for arc length computation.
