voronoi.area

Calculate area of Voronoi polygons

Description

Computes the area of each Voronoi polygon. For some sites at the edge of the region, the Voronoi polygon is not bounded, and so the area of those sites cannot be calculated, and hence will be NA.

Usage

voronoi.area(voronoi.obj)

Arguments

voronoi.obj

object of class "voronoi"

Value

A vector of polygon areas.

Author(s)

S. J. Eglen

Examples

data(tritest)
tritest.vm <- voronoi.mosaic(tritest$x,tritest$y)
tritest.vm.areas <- voronoi.area(tritest.vm)
plot(tritest.vm)
text(tritest$x, tritest$y, tritest.vm.areas)
