digest creates hash digests of arbitrary R objects (using the
spookyhash algorithms) permitting easy comparison of R language objects.
This version contains two new functions adding new digest functionality. First, Dmitriy Selivanov added a fast and vectorized
digest2int to convert (arbitrary) strings into 32 bit integers using one-at-a-time hashing. Second, Kendon Bell, over a series of PRs, put together a nice implementation of spookyhash as a first streaming hash algorithm in digest. So big thanks to both Dmitriy and Kendon.
