I wanted to follow up on this thread from a few months ago about BLAS options in the current R package.
Simon, is it possible to go forward with one of the following two options? 1) leave libRblas.vecLib.dylib out of the R package (AFAIK this is how things currently stand in the 3.0.2 pkg) but update this FAQ ( http://cran.r-project.org/bin/macosx/RMacOSX-FAQ.html#Which-BLAS-is-used-and-how-can-it-be-changed_003f) to tell folks that they can enable vecLib BLAS by symlinking the Accelerate framework as: cd /Library/Frameworks/R.framework/Versions/Current/Resources/lib ln -s /System/Library/Frameworks/Accelerate.framework/Versions/Current/Frameworks/vecLib.framework/Versions/Current/libBLAS.dylib libRblas.dylib 1a) Our systems administrator here suggested the additional possibility of have the R installer have an option (perhaps under the Customize button at the point where "Installation Type" is chosen) that the user could select to have switching to vecLib be done as part of the install. 2) Return libRblas.vecLib.dylib to the R package, in which case the current FAQ will then be accurate.
