Implementation in R of the alphashape of a finite set of points in the threedimensional space. The alphashape generalizes the convex hull and allows to recover the shape of nonconvex and even nonconnected sets in 3D, given a random sample of points taken into it. Besides the computation of the alphashape, this package provides users with functions to compute the volume of the alphashape, identify the connected components and facilitate the threedimensional graphical visualization of the estimated set.
