bdist.tiles {spatstat.geom}

R Documentation

Distance to Boundary of Window

Description

Computes the shortest distances from each tile in a tessellation to the boundary of the window.

Usage

 bdist.tiles(X)

Arguments

X	A tessellation (object of class "tess").

Details

This function computes, for each tile s_i in the tessellation X, the shortest distance from s_i to the boundary of the window W containing the tessellation.

Value

A numeric vector, giving the shortest distance from each tile in the tessellation to the boundary of the window. Entries of the vector correspond to the entries of tiles(X).

Examples

  P <- runifrect(15)
  X <- dirichlet(P)
  plot(X, col="red")
  B <- bdist.tiles(X)
  # identify tiles that do not touch the boundary
  plot(X[B > 0], add=TRUE, col="green", lwd=3)
