[R] currency or stock trading strategy

[Darren Weber]

Hi,

are there any good charting and analysis tools for use with
currencies, stocks, etc. in R?  I have some tools to download currency
data from the NYFRB using python and XML.  Can we get and parse an XML
download using R?  Can we have interaction in R plots?  Does anyone
use R for back-testing trading strategies?  Are there any forums for
discussion of using R for this specific purpose (apart from this
general list)?  Is anyone aware of any general open-source
developments for these purposes (I don't see any from GNU or google
searches)?

Take care, Darren
