The Stark-Parker algorithm for bounded-variable least squares

Description

An R interface to the Stark-Parker implementation of an algorithm for bounded-variable least squares that solves \min{\parallel A x - b \parallel_2} with the constraint l \le x \le u, where l,x,u \in R^n, b \in R^m and A is an m \times n matrix.
