I have created a collection of patches to the R 2.13.0 source that speed up many operations substantially. Some of these are related to the patches I posted in September 2010, though often with additional improvements. Other patches are new.

The patches, along with detailed documentation, are available from


For some discussion of these patches and their benefits, see my blog post, at


I believe that these improvements to the R implementation should be of substantial benefit to the R community. The R core team is welcome to incorporate them into versions of R that they release in the future.
