Rcpp Interface to the Google FarmHash Family of Hash Functions

Motivation

Google BigQuery uses FarmHash in its FARM_FINGERPRINT function. By using the same underlying FarmHash library, this package allows R users to compute the same hash digest fingerprints.

Example

> suppressMessages({ library(RcppFarmHash); library(bit64) })
> farmhash(c("foo", "bar", "baz"))
