[R-SIG-Mac] Linking R 4.0 to an alternative BLAS

[Braun, Michael]

Under R 3.6.3 and earlier, I would link R to an alternative BLAS. Following R for Mac FAQ, Sec. 10.5, I would redirect the symbolic link $R_HOME/lib/libRblas.dylib to point to whichever BLAS  I wanted to use, (either vecLib or Intel MKL) instead of the reference BLAS at libRblas.0.dylib.

With the R 4.0.0 precompiled binaries from CRAN, under $R_HOME/lib,  libRblas.dylib is the reference BLAS itself, and there is no libRblas.0.dylib file.  Is this by design?  Is there an officially recommended alternative?

Thanks,

MB
