R: Compute Areas of Tiles in a Tessellation

tile.areas {spatstat} | R Documentation

## 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.

      E <- tess(image=v)
      tile.areas(E)
