dirichlet: Dirichlet Tessellation of Point Pattern

Description

Computes the Dirichlet/Voronoi tessellation of a spatial point pattern.

Usage

dirichlet(X)

Arguments

X

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

Value

• A tessellation (object of class "tess").

Details

In a spatial point pattern X, the Dirichlet/Voronoi tile associated with a particular point X[i] is the region of space that is closer to X[i] than to any other point in X. The Dirichlet tiles divide the two-dimensional plane into disjoint regions, forming a tessellation.

This function computes the Dirichlet tessellation (within the original window of X).

Examples

X <- runifpoint(42)
  plot(dirichlet(X))
  plot(X, add=TRUE)
