rcdd (Computational Geometry)
Charles J. Geyer <charlie@stat.umn.edu> and Glen D. Meeden <glen@stat.umn.edu>, incorporates code from cddlib (ver 0.94f) written by Komei Fukuda <fukuda@ifor.math.ethz.ch>
GPL (>= 2)
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.
