Kevin,

This is a nice start. I'll Cc this back to the recently formed 'R in
Finance' list we formed as a result of the two Finance sessions at use useR.

One small correction would be that the number of CRAN packages is now in
excess of 350 (not 150).

And a point you may want to add is that the S language has been used in some
geek corners of Finance for decades; the proximity of Bell Labs to Wall St
may have something to do with that, as does of course the power and elegance
of the language.

S-Plus also offers some fancypants add-on modules, and we'll try hard over
the next few months and years to catch up. A major help in that regard is
Diethelm Wuertz' most excellent Rmetrics collection at

http://www.rmetrics.org

This is currently windows-only, but Diethelm and I are committed to getting
it into Debian (and my Quantian) so that general Unix/Linux use should fall
out as a side benefit.

Hope this helps, Dirk
