Description

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

Usage

bdist.tiles(X)

Value

  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)
