⚠️There's a newer version (0.4.24) of this package.Take me there.

RProtoBuf (version 0.4.2)

R Interface to the Protocol Buffers API

Description

Protocol Buffers are a way of encoding structured data in an efficient yet extensible format. Google uses Protocol Buffers for almost all of its internal RPC protocols and file formats. Additional documentation is available in the arXiv.org preprint "RProtoBuf: Efficient Cross-Language Data Serialization in R" by Eddelbuettel, Stokely, and Ooms (2014) http://arxiv.org/abs/1401.7372
