A new and much enhanced version of RcppMsgPack arrived on CRAN a couple of days ago. It came together following this email to the r-package-devel list which made it apparent that Travers Ching had been working on MessagePack converters for R which required the very headers I had for use from, inter alia, the RcppRedis package.
So we joined our packages. I updated the headers in RcppMsgPack to the current upstream version 2.1.5 of MessagePack, and Travers added his helper functions allow direct packing / unpacking of MessagePack objects at the R level, as well as tests and a draft vignette. Very exciting, and great to have a coauthor!
So now RcppMspPack provides R with both MessagePack header files for use via C++ (or C, if you must) packages such as RcppRedis --- and direct conversion routines at the R prompt.
MessagePack itself is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON. But it is faster and smaller. Small integers are encoded into a single byte, and typical short strings require only one extra byte in addition to the strings themselves.
Changes in version 0.2.0 (2017-09-07)
Added support for building on Windows
Upgraded to MsgPack 2.1.5 (#3)

A new minor release of RcppRedis arrived on CRAN last week, following the release 0.2.0 of RcppMsgPack which brought the MsgPack headers forward to release 2.1.5. This required a minor and rather trivial change in the code. When the optional RcppMsgPack package is used, we now require this version 0.2.0 or later.
We made a few internal updates to the package as well.
Changes in version 0.1.8 (2017-09-08)
A new file
init.cwas added with calls toR_registerRoutines()andR_useDynamicSymbols()Symbol registration is enabled in
