Hi All,
Before these things be set in stone, it should be noted that it would be a
real mistake to have a miscalculated statistical object on R's Homepage.
Imagine if SAS found out!

That's not really in the spirit of R. Normally one works with
whole objects at a time. You might wish to rethink your
