I've been teaching myself R now that I finally got Rapidminer's R plugin to work. Â It's Â pretty slick program and easy to learn, I've picked up so many things quickly. Â I extensively use the PerformanceAnalytics, Quantmod, and tseries packages for R and on top of that, I started to recreate AÂ Physicist on Wall Street'sÂ awesome Rapidminer + R Example for Trading tutorial. So far so good.
It's fantastic that I can now download stock quotes, using the R plugin, right into Rapidminer and then model those time series. Â Yes the native R software has a few learning algorithms, but they in no way match Rapidminer's breadth and depth. Â That, and with Rapidminer's ability to handle large data sets effeciently, and R's statistical analytic and graphing powers, makes the Rapidminer and R combination a disruptive technology in my book.
Download it today, play with it, it will make your data shine in ways you can only dream of.
