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).
