delaunayNetwork: Linear Network of Delaunay Triangulation or Dirichlet Tessellation

Description

Computes the edges of the Delaunay triangulation or Dirichlet tessellation of a point pattern, and returns the result as a linear network object.

Usage

delaunayNetwork(X)

dirichletNetwork(X, …)

Arguments

X

A point pattern (object of class "ppp").

Arguments passed to as.linnet.psp

Value

Linear network (object of class "linnet") or NULL.

Details

For delaunayNetwork, points of X which are neighbours in the Delaunay triangulation (see delaunay) will be joined by a straight line. The result will be returned as a linear network (object of class "linnet").

For dirichletNetwork, the Dirichlet tessellation is computed (see dirichlet) and the edges of the tiles of the tessellation are extracted. This is converted to a linear network using as.linnet.psp.
