tile.areas: Compute Areas of Tiles in a Tessellation

Description

Computes the area of each tile in a tessellation.

Usage

tile.areas(x)

Value

A numeric vector.

Arguments

x

A tessellation (object of class "tess").

Author

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).

Examples

  A <- tess(xgrid=0:2,ygrid=0:2)
  tile.areas(A)
  v <- as.im(function(x,y){factor(round(x^2 + y^2))}, W=owin())
  E <- tess(image=v)
  tile.areas(E)
