Hi Folks,
Sorry to raise what has probably been discussed before, but I an repeatedly struck by the comparative slowness of S-plus for Windows compared with R for Linux when doing much the same thing.
I don't have a direct comparison, because they're not running on the same machine; but machine W has a faster CPU and more RAM than machine L, yet S-plus on W seems to take longer by quite a big factor (of the order of 5x) than R on L.
My instincts say that "WIndows" is probably a significant factor in the comnparison, but still ...
Ideally, to compare R with S-plus, one should look at them both on the same OS (Unix or Windows) on the same machine.
Can anyone give me clean comparative speeds?
It heavily depends on what you are doing, and on the versions of R and S-PLUS.
Given you do not link R against very specialized libraries such as ATLAS on one and not the other OS, I found no dramatic differences between R on Linux and Windows, but that might depend on the application as well.
