R: Use faster vecLib
These code snippets have been tested on R 3.1.0 and Mac OS 10.9.3. They presumably do *not* work on R 2.X!
## Enter these commands in the Mac OS Terminal
# use faster vecLib library
cd /Library/Frameworks/R.framework/Resources/lib
ln -sf /System/Library/Frameworks/Accelerate.framework/Frameworks/vecLib.framework/Versions/Current/libBLAS.dylib libRblas.dylib
# return to default settings
cd /Library/Frameworks/R.framework/Resources/lib
ln -sf libRblas.0.dylib libRblas.dylib
# R script for benchmarking:
# http://r.research.att.com/benchmarks/R-benchmark-25.R
# On 2011 Macbook Pro (2.7 GHz Core i7): 43 sec. (Rblas) vs. 9 sec. (vecLib)
