I haven't gotten around to assembling the toolset required to build R on Windows, since most of what I do is smallish interactive problems. However, another possibility would be to load CygWin/XFree86 on your laptop (which I've done), then download Atlas 3.5.7 from SourceForge (which I've done), then build Atlas with CygWin(which I've done) and then build a second version of R under CygWin using Atlas, and use the CygWin/Atlas R for the heavy number-crunching jobs. This last I haven't done, so I can't say whether there are any gotchas, but everything else I've done with CygWin/XFree86 has worked. My laptop is a Compaq Presario with a 1.67 GHz Athlon XP. Atlas screams on it; the Atlas folks were grinning when I sent them the log. Atlas has an assembly language kernel for Athlons (and P4s as well IIRC).
Oh, yeah ... If you do try my scheme, make sure you don't have spaces in the paths ... Atlas still isn't immune to that sort of thing under CygWin. -- M.
