R Project Updates

Updates from R Core:

• Fix problems in command completion: Crash (PR#17222) and junk display in Windows, handling special characters in filenames on all systems.

• callNextMethod() was broken when called from a method that augments the formal arguments of a primitive generic.

• Coercion of an S4 object to a vector during sub-assignment into a vector failed to dispatch through the as.vector() generic (often leading to a segfault).

• One can now choose from alternative matrix product implementations via options(matprod = ). The "internal" implementation is not optimized for speed but consistent in precision with other summations in R (using long double accumulators where available). "blas" calls BLAS directly for best speed, but usually with undefined behavior for inputs with NaN/Inf.
