CRC32C is a cyclic redundancy check (with parity) implementation based on work by Castagnoli, Brauer, and Hermann that is provided by Google in a repository with optional hardware-acceleration selected at run-time. It is included (minus the parts for logging, testing and benchmarking we would not use from R) 'as is' in the package at src/crc32c/.
This project provides it for use by R. We also aim for this to be an
example of how a standalone cmake project providing a library can be offered via an R package for
use by R as well as by other R packages.
The package provides a function direct callable from R.
The package also exports three C-level functions that can be called directly from other R packages by means of a mechanism described in Writing R Extensions.

For the R package integration and maintenance, Dirk Eddelbuettel
