Package: rcdd 1.6

Charles J. Geyer

rcdd: Computational Geometry

R interface to (some of) cddlib (<https://github.com/cddlib/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.

Authors:Charles J. Geyer <geyer@umn.edu> and Glen D. Meeden <gmeeden@umn.edu>, incorporates code from cddlib written by Komei Fukuda <fukuda@ifor.math.ethz.ch>
