walkr: Random Walks in the Intersection of Hyperplanes and the N-Simplex

Consider the intersection of two spaces: the complete solution space to Ax = b and the N-simplex. The intersection of these two spaces is a non-negative convex polytope. The package walkr samples from this intersection using two Monte-Carlo Markov Chain (MCMC) methods: hit-and-run and Dikin walk. walkr also provide tools to examine sample quality.

Install the latest version of this package by entering the following in R:
install.packages("walkr")
