[R-sig-finance] R and exchanges

I sent a question to the general Help. I received an answer from Patrick
Burns, and he suggested me to post it here. The question is how to use batch
files that call R in an effective way. More:

What I need is to interact with other applications(a connection to
exchanges, like Eurex, Liffe, CBOT and eventually to something like ESB in
FX). So, if I get a price from the exchanges, I want that R makes a
calculation. But to get R connected to the exchanges is complex, so what I
have thought is to have an external program that connects to the exchanges,
then gets the prices and saves them to a txt file, then R is opened, the txt
file is read, the calculations are performed, and the results are saved into
another txt file. Then, another application reads the new txt file and sends
a message to the exchanges.

This is what I want to do.

Does anybody have some ideas about it?

Thank you!
