Hello,

I did this bechmark test. Perhaps is it a good oppotunity to rewrite it and make it compatible with R 2.7.0, David? Best,

I wonder if anyone has a more rigorous benchmarking program for R. I downloaded a old R test/benchmarking program (see below), and this didn't work with the current R, and so I wondered if anyone could please direct me to a more recent program that does a good all round test of R.
