### Motivation

Google BigQuery uses FarmHash in its `FARM_FINGERPRINT` function. By using the same

underlying [FarmHash](https://github.com/google/farmhash) library, this package allows R

users to compute the same hash digest fingerprints.

### Example

```r

> suppressMessages({ library(RcppFarmHash); library(bit64) })

> farmhash(c("foo", "bar", "baz"))

integer64

>

```

### Installation

The package can be installed from CRAN via the usual command

```r

install.packages("RcppFarmHash")

```

or, alternatively, also directly from the source repository:

```r

remotes::install_github("eddelbuettel/rcppfarmhash")

```
