toyPattern

<p>A simulated object of class <code>"ppp"</code> provided for use
    in an example illustrating the application of <code>deldir()</code>
    to point pattern objects.</p>

datasets

Calculates the Delaunay triangulation and the Dirichlet
or Voronoi tessellation (with respect to the entire plane) of
a planar point set. Plots triangulations and tessellations in
various ways.  Clips tessellations to sub-windows. Calculates
perimeters of tessellations.  Summarises information about
the tiles of the tessellation.	Calculates the centroidal
Voronoi (Dirichlet) tessellation using Lloyd's algorithm.
