R: Calculate area of Voronoi polygons

voronoi.area {interp} | R Documentation

## 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.

### Examples

    data(franke)
    fd3 <- franke$ds3
    fd3.vm <- voronoi.mosaic(fd3$x,fd3$y)
    fd3.vm.areas <- voronoi.area(fd3.vm)
    plot(fd3.vm)
    text(fd3$x, fd3$y, round(fd3.vm.areas,5))
