Implements efficient\n'C++' backends for the 'focus', 'md-focus' and 'np-focus'\nalgorithms, with an 'R' interface for real-time monitoring and\noffline analysis. The package bundles code from 'Qhull'\n<http://www.qhull.org/>, by C. B. Barber and The Geometry\nCenter. See 'inst/COPYRIGHTS' for details.",
