I have been doing data analysis for over 25 years, using many different products. Ruby, from Red Centre Software is by far the best for many reasons. Some of the reasons are, it is blindingly fast, it has functions and utilities that make importing any sort of data a breeze. It has been developed from a data analyst’s perspective, not a programmer guessing what is needed in a data analysis package. It makes a real difference. When used with VB.net Express it really rocks, it has intellisense, step through debugging, colour coded auto-formatting. I can even interface it to our SQL server on the web. The productivity gains we have enjoyed, together with faster turnaround times our clients enjoy. Ruby is one of our main competitive edges.
