In hrbrmstr/hrbrmiscpp: hrbrmiscpp title goes here

Description

This algorithm was created for sdbm (a public-domain reimplementation of ndbm) database library. it was found to do well in scrambling bits, causing better distribution of the keys and fewer splits. It also happens to be a good general hashing function with good distribution.

Usage

sdbm_hash(x)

Arguments

x	character vector of strings to hash

Value

numeric vector of the hashes of x
