A new version 0.3.2 of RProtoBuf, is now on CRAN. RProtoBuf provides GNU R bindings for the Google Protobuf data encoding library used and released by Google.

As for the last few releases, Murray took charge of most changes. The NEWS file entry follows:

Changes in RProtoBuf version 0.3.2 (2013-12-15)

• Fixed a bug that erroneously prevented users from setting raw byte fields in protocol buffers under certain circumstances.

• Give a user friendly error message when seting an extension to a message of the wrong type instead of causing a C++ check failure that terminates the Rsession.

• Change object table lookup slightly to allow users to use the <<- operator in code using RProtoBuf without hitting a stop() error in the lookup routine.

• Add missing enum_type method and improve show method for EnumValueDescriptors.

• Improve documentation and tests for all of the above.

• Rewrote tests/ script calling RUnit tests

CRANberries also provides a diff to the previous release 0.3.1. More information is at the RProtoBuf page which has a draft package vignette, a 'quick' overview vignette and a unit test summary vignette. Questions, comments etc should go to the rprotobuf mailing list off the RProtoBuf page at R-Forge.
