Hi all, I have update my benchmark test suite to version 2 that now uses R as the reference software (http://www.sciviews.org/other/benchmark.htm). Results concern R 1.7.0 under Windows XP, compared to S-PLUS, Matlab, Octave, Scilab, O-Matrix and Ox. Testing data analysis software for speed is just one part of the problem (a current thread is dealing, for instance, with QA which is a different aspect). However, this benchmark could be informative, keeping its limitations in mind.
