This release also marks support of the 64-bit Windows platform by the R Project for the first time. With the assistance of members of the R Core Group. REvolution Computing pioneered support for R on 64-bit Windows: it’s major platform of our REvolution R Enterprise product and has been for almost 2 years. While R 2.11.0 is built using the free mingw compiler, REvolution R Enterprise is built using a commercial toolchain, and links to multi-threaded libraries for improved processing speed on multi-core systems.
