Quote from trader#21:
I tried R but it was frustrating. A simple heatmap which takes few clicks in Excel can take full weekend in R.
Most of the stuff I (and most non-quant) traders need is overwhelmingly simple. What takes 100 lines to backtest in Multicharts can take... well, lots of sweat.. in R (or matlab for that matters).
If you can provide links to some newsgroups/resources on R graphics it will be much appreciated.
Trust me (and dtrader98, and 100s of other actual folks who use R for trading) : you gave up too soon. Check out http://www.quantmod.com for the kind of simple stuff you might think is more practical/realistic than heatmaps, etc;
