Dear Josh and all other R-SIG-Finance members;

This is my first post to the group and I recognize that it is not directly
related to R and finance, but as something of an Open Source advocate I am
sensitive to comments like "In finance, EXCEL dominates over any products."
While this may be true for volume of sales, marketing hype and general
public acceptance, my understanding is that it is not the best product for
statistical precision, responsiveness of the company producing it to
correcting known errors, or adherence to good graphical standards.

Here are references to two easily found websites which discuss limitations
of EXCEL for use in general statistics and more specifically in statistical
finance.

Practical Stats - Statistics With Excel <
http://www.practicalstats.com/xlsstats/excelstats.html>

Burns Statistics - Spreadsheet Addiction <
http://www.burns-stat.com/pages/Tutor/spreadsheet_addiction.html>

Again, as a lurker on the group I ask for your forbearance for a reply on a
topic only remotely related to R and finance and would like to thank Brian,
Dirk, Jeff, Diethelm and many other who take the time to make this such an
interesting place to check in on a couple of times a day.
