[R-sig-finance] R and Prompt

[roger bos]

Gabor suggestions will work, but I would also recommend looking at the
Rpad library.  Rpad allows a web page to communicate with R, so you
can design the page however you want and the users just puts in the
parameters and hits calculate.  In your approach, everyone who uses
the program would have to have R installed.  With Rpad, only the web
server has to have R and everyone else connects through the web page.

HTH,
Roger
