R: Distance to Boundary of Window

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)`.

      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)
