rcdd: rcdd (Computational Geometry)
R interface to (some of) cddlib
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.
