cart2pol

x-coordinates or matrix with three columns

y-coordinates (optional, if <code>x</code>) is a matrix

z-coordinates (optional, if <code>x</code>) is a matrix

The inputs <code>x</code>, <code>y</code> (, and <code>z</code>) must be the same shape, or
scalar. If called with a single matrix argument then each row of <code>C</code>
represents the Cartesian coordinate (<code>x</code>, <code>y</code> (, <code>z</code>)).

Makes the 'Qhull' library <http://www.qhull.org>
available in R, in a similar manner as in Octave and MATLAB. Qhull
computes convex hulls, Delaunay triangulations, halfspace
intersections about a point, Voronoi diagrams, furthest-site
Delaunay triangulations, and furthest-site Voronoi diagrams. It
runs in 2D, 3D, 4D, and higher dimensions. It implements the
Quickhull algorithm for computing the convex hull. Qhull does not
support constrained Delaunay triangulations, or mesh generation of
non-convex objects, but the package does include some R functions
that allow for this.
