Hi,
In rw-FAQ, there is a paragraph about optimizing R by using a fast ATLAS
library in place of the standard BLAS. It says: "BLAS support is supplied
by
the single DLL `R_HOME\bin\Rblas.dll', and
you can add a fast BLAS just by replacing that." Do I need to recompile the
whole R with the option `USE_ATLAS = YES', or is it possible to compile only
Rblas.dll on each separate computer (with different processors)?
Thanks,
Philippe Grosjean

And it says so in the INSTALL file, giving make commands to do so. -- Brian D.
