I learned about the internals of lm from Whit Armstrong, Ajay Shah provided
tests/vcovHAC.R and demo/dyn-MCMCpack.R is modified from code by Delali
Accolley developed.  Also this package would not be possible without the
useful discussions with:

  Delali Accolley <accolleyd@excite.com> - demo/dyn-MCMCpack.R
  Whit Armstrong <Whit.Armstrong@tudor.com> - lm internals
  Matthieu Cormec <matthieu.cormec@gmail.com>
  Leila Farivar <farivar@uiuc.edu>
  Roger Koenker <rkoenker@uiuc.edu>
  Andy Liaw <andy_liaw@merck.com>
  David Meyer <david.meyer@wu-wien.ac.at>
  Ajay Shah <ajayshah@mayin.org> - tests/vcovHAC.R
