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 <[email protected]> and Glen D. Meeden <[email protected]>, incorporates code from cddlib written by Komei Fukuda <[email protected]>
