Computation of the \(\alpha\)-shape and \(\alpha\)-convex hull of a given sample of points in the plane. The concepts of \(\alpha\)-shape and \(\alpha\)-convex hull generalize the definition of the convex hull of a finite set of points. The programming is based on the duality between the Voronoi diagram and Delaunay triangulation. The package also includes a function that returns the Delaunay mesh of a given sample of points and its dual Voronoi diagram in one single object.
