The R Core team today announced the release of R 3.4.2. This release fixes a number of minor bugs and also includes a performance improvement to the commonly-used function c when applied to vectors with a names attribute. Like all minor releases, this release is backwards compatible with prior releases in the R 3.4.x series. Binary builds of R 3.4.2 will begin to appear on your local CRAN mirror within the next day or so.
This release also marks the final Windows build of R by Duncan Murdoch, who has been volunteering his time to the R Core group for more than 15 years to build R (and its companion Rtools) for Windows. Along with the rest of the team here at Microsoft, I'd like to offer a hearty THANK YOU to Duncan for his time, effort and expertise over these years to bring R to the Windows community.
