I'll not really rewrite it (to make it "nice" in my eyes),
but I'm fixing the problems with the fact that the 'Matrix'
package you were using back then has been much changed in the
mean time.

Expect a corrected benchmark R script within a day or so.

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.
