Linear Network of Delaunay Triangulation or Dirichlet Tessellation

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

Keywords
manip, spatial
Usage
delaunay.network(X)

dirichlet.network(X, ...)

Arguments
X
A point pattern (object of class "ppp").
...
Arguments passed to as.linnet.psp
Details

For delaunay.network, 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 dirichlet.network, 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.

Value

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