Robust Regression Package for R

I wrote this package in 2006 when the major statistical software companies did not have a robust regression package available.  It has been downloaded over 100k times.  Using iteratively reweighted least squares (IRLS), the function calculates the optimal weights to perform m-estimator or bounded influence regression. Returns robust beta estimates and prints robust ANOVA table using either a Huber or bisquare function.

Recent changes make the structure of the arguments similar to glm() or lm() and speed has dramatically increased.
