Two months to the day after the previous
0.3.0
release of
RProtoBuf,
we are happy to announce a maintenance release 0.3.1 which has
now arrived on CRAN.
RProtoBuf
provides GNU R
bindings for the
Google Protobuf data encoding
library used and released by Google.

Once again, Murray lead this release
and added a number improvements. The NEWS file entry follows:

Changes in RProtoBuf version 0.3.1 (2013-09-13)

• Added support for setting and getting 64-bit integer types as
  character strings of decimal integers to work around R’s lack of native
  64-bit integer types.

• Added better error handling, documentation, and tests to the
  extensions support (getExtension and setExtension).

• Add support to P for returning extension descriptors.

• Improved error messages to include field names when invalid
  fields are specified to protocol buffer messages with new, update, etc.

• Improved configure to detect and pass -std=c++0x if it is
  available to enable long long 64-bit integer support in Rcpp.

• Improved configure in the case when pkg-config is not
  available or does not know about the google protocol buffer
  includes.

• Replaced newly deprecated Rcpp macros with a simplified macro
  functionality to avoid warnings on the latest development version of
  Rcpp.

CRANberries also provides a

diff to the previous release 0.3.0.
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.
