Dirichlet Tessellation of Point Pattern

Description

Computes the Dirichlet tessellation of a spatial point pattern.

Usage

dirichlet(x)

Arguments

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

Details

In a spatial point pattern x, the Dirichlet 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).

Value

A tessellation (object of class "tess").
