Please tell your e-mail software to send plain text messages to lists 
like this.
Please upgrade to the recent version, R-1.8.1, since many bugs are fixed 
  and a lot of features have been introduced.
Please note that lda() and qda() are in package MASS in the VR package 
bundle, not in R itself.
Finally, documentation does not mention 'cov.mcd' in the recent version 
of the VR bundle.
