influence_of: Influence Of Internal Knots

In cpr: Control Polygon Reduction

Description

Given a control polygon and set of indices, return the influence weight for the specified internal knots and generate graphics showing the original, coarsened, and approximated control polygons.

Usage

influence_of(x, indices, ...)

Arguments

x	a cpr_cp object
indices	an integer vector specifying the elements of attr(x, "knots") to assess. Defaults to all internal knots.
...	Additional arguments passed to influence_weights.

Value

A cpr_influence_of object. This is a list with the following elements:

weight

A tibble (data.frame) showing the influence weight and relative rank of each internal knot

orig_cp

The original control polygon

indices

The indices of the internal knots assessed.

coarsened_cp

A list of control polygons. These are the control polygons built on the coarsened knot sequence

reinserted_cp

A list of control polygons. These are the control polygons resulting from the reinsertion of the assessed internal knot.
