In eddelbuettel/rcppmsgpack: 'MsgPack' C++ Header Files and Interface Functions for R

RcppMsgPack

Convert to and from msgpack objects in R using the official msgpack-c API through Rcpp.

{width=700px} A flowchart describing the conversion of R objects into msgpack objects and back.

Msgpack EXT types are converted to raw vectors with EXT attributes containing the extension type. The extension type must be an integer from 0 to 127.

Maps are converted to data.frames with additional class "map". Map objects in R contain key and value list columns and can be simplified to named lists or named vectors. The helper function msgpack_map creates map objects that can be serialized into msgpack.

For more information on msgpack types, see here.
