tile.areas {spatstat.geom}

Compute Areas of Tiles in a Tessellation

Description

Computes the area of each tile in a tessellation.

Usage

tile.areas(x)

Arguments

x

A tessellation (object of class "tess").

Details

A tessellation is a collection of disjoint spatial regions (called tiles) that fit together to form a larger spatial region. See tess.

This command computes the area of each of the tiles that make up the tessellation x. The result is a numeric vector in the same order as the tiles would be listed by tiles(x).

Value

A numeric vector.
