GitHub - eddelbuettel/rcppfarmhash: Rcpp Interface to Google FarmHash (original) (raw)

Rcpp Interface to the Google FarmHash Family of Hash Functions

suppressMessages({ library(RcppFarmHash); library(bit64) }) farmhash(c("foo", "bar", "baz")) integer64 [1] 6150913649986995171 -98778129085727977 3758908700204700005
