Call for Participation
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 subassignment 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 (usinglong double
accumulators where available)."blas"
calls BLAS directly for best speed, but usually with undefined behavior for inputs withNaN
/Inf
.
