RProtoBuf 0.2.6

Release 0.2.6 of RProtoBuf arrived on CRAN earlier this morning. RProtoBuf provides GNU R bindings for the Google Protobuf data encoding library used and released by Google.

This release was once more driven largely by Murray whom we have now added among the list of authors of the package too. The NEWS file entry follows below:

Changes in version 0.2.6 (2012-10-04)

  • Applied several more patches by Murray to

    • correct '_' and '__' mismatches in wrapper calls

    • update a few manual pages for style, and add examples

    • fix a bug where NAs were silently treated as TRUE for logical/bool types

    • fix a bug that caused crashes when adding vectors to optional fields

    • fix bugs in readASCII that returned empty protocol buffers when the file or connection could not be opened

    • distinguish between non-existant and not-set fieldswith has() by returning NULL in the former case.

    • fix a bug that caused non-deterministic behavior when setting a repeated message field in a protobuf to a single Message.

    • add unit tests for all of the above.

  • Added Murray to Authors: field in DESCRIPTION

  • Removed old and unconvincing example on RProtoBuf for storage and serialization in an imagined HighFrequencyFinance context

CRANberries also provides a diff to the previous release 0.2.5. 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.
