[Rd] Debate: Shall some of Microsoft R Open Code be ported to mainstream R?

I think the thing that is missing is a simple way for end users on windows to replace blas/lapack libraries with MKL-a package that you install that puts the libraries in the right place.

Microsoft provides something for their distro, but we don't have the equivalent if you get R from cran.

With all due respect: You may miss something. MKL has always worked with 'Base R'.

As a point of reference and comparison, I set up a benchmarking and

comparison package _well over half a decade ago_ and while it never get fully

finished to the point of a submitted paper the vignette still stands---and

demonstrates that _dropping in MKL is a one-line operation_.

And always has been.  There may have been some license arbitrage: Intel was

an early investor in Revo, so MKL was pushed hard.  With GotoBLAS and later

OpenBLAS I cared less, but IIRC the license of MKL is a little simpler for

"mere use" now.
