I like R but some problems really run into performance problems with R. In particular snowballing memory if not possible to convert data to enum/factors, and predictions with lots of Date data really skyrocket memory use. I like to play in the kaggle.com competitions, and I'm thinking of switching over more stuff I do there from R to waffles, which is a toolset and a c++ lib. It's speedy, and rather user friendly. http://waffles.sourceforge.net/ http://waffles.sourceforge.net/
