  "Description": "Implementation in R of the alpha-shape of a finite set of\npoints in the three-dimensional space. The alpha-shape\ngeneralizes the convex hull and allows to recover the shape of\nnon-convex and even non-connected sets in 3D, given a random\nsample of points taken into it. Besides the computation of the\nalpha-shape, this package provides users with functions to\ncompute the volume of the alpha-shape, identify the connected\ncomponents and facilitate the three-dimensional graphical\nvisualization of the estimated set.",
