Distance to Boundary of Window
Computes the shortest distances from each tile in a tessellation to the boundary of the window.
bdist.tiles(X)
X |
A tessellation (object of class |
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.
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).
