Update Information:
R now uses openblas instead of the unoptimized blas bundled with R (on all
architectures where openblas is supported). In the previous update, this was
done by symlinking /usr/lib64/R/lib/libRblas.so to /usr/lib64/libopenblas.so.0.
While this worked fine for R, it did not work for anything linking to libR.so or
trying to dynload libRblas.so. To resolve this, a new openblas subpackage
(openblas-Rblas) has been added, which contains a copy of openblas built as
libRblas.so (and reporting libRblas.so as its soname). R now depends on
openblas-Rblas on all architectures which support openblas and on all targets
new enough to build openblas (RHEL 7+, Fedora 23+). Older targets or
incompatible architectures use the unoptimized Rblas. If you wish to switch
from the openblas libRblas.so to the R provided blas, simply rename
/usr/lib64/R/lib/libRrefblas.so to /usr/lib64/R/lib/libRblas.so.
