...(http://math-atlas.sourceforge.net/)) tuned to your system for fast linear algebra routines. Pre-built `Rblas.dll' for various Pentium and AthlonXP chips are available in the `windows/contrib/ATLAS' area on CRAN. If you are building R from source, there are macros `USE_ATLAS' and `ATLAS_PATH' in the file `MkRules'. Set `USE_ATLAS = YES' and `ATLAS_PATH' to where the ATLAS libraries are located. You will need to make the libraries yourself(1): none of the binaries we have seen are compiled for the correct compiler. Since R...

In the file MkRules.local.in, I see the line: USE_ATLAS = NO which I believe needs to be changed to YES. But how do I specify the BLAS file *libopenblas_haswell-r0.2.20.a *and its location?

...Q, 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)?

Hi All, I am trying to compile R from source on a 64 bit Windows. I have downloaded and installed all the third party software as per the R - documentation. The compilation starts fine and after a while it stops with the following error message: D:/Rtools/mingw_64/bin/../lib/gcc/x86_64-w64-mingw32/4.9.3/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lRgraphapp collect2.exe: error: ld
