rcdd (Computational Geometry)
Description
R interface to (some of) cddlib
(http://www.ifor.math.ethz.ch/~fukuda/cdd_home/cdd.html).
Converts back and forth between two representations of a convex
polytope: as solution of a set of linear equalities and
inequalities and as convex hull of set of points and rays. Also
does linear programming and redundant generator elimination
(for example, convex hull in n dimensions). All functions can
use exact infinite-precision rational arithmetic.
