I recently started learning R and found it to be a very good substitute for Matlab and other statistical software. Came a cross this very nice package for downloading stock prices directly to R and have it draw some nice graphs, that I thought others on nexusfi.com (formerly BMT) might find useful.

getSymbols("IBM")
chartSeries(IBM, subset='last 3 months')
addBBands()
