Re: [Rd] Problem with tuned Rblas from CRAN with R-2.4.0

I just ran the example on a Win2000/P4 BLAS DLL system. It works fine on 2.4.1 beta (2006-12-10 r40146) as well as 2.5.0 Under development (unstable) (2006-12-10 r40146).

I have had the same DLL file for a couple of years now (downloaded from the Wisconsin CRAN if I remember correctly) but occasionally I check the file sizes between the one available on CRAN and the one I have and the size (in bytes) seems to stay the same.

I just looked into the one for P4 and it does export zdrot_ and works for me. Is your one from CRAN master?

downloaded from CRAN (data from R-help post by Ethan Johnsons). I was also using the contributed binary Rblas.dll for Intel P4 chip. The problem doesn't occur with the default Rblas.dll.

I checked the changes file and saw that for R-2.4.0 the Rblas.dll would have to be recompiled, but also that the contributed binaries on CRAN had been updated. However, I couldn’t find any Rblas binaries with a date after 2005. Any suggestions on where to find an Rblas binary for WinXP and P4 chip, or do I need to try to compile one on my own?
