The digest2int function calculates integer hash of an arbitrary string. This is useful for randomized experiments, feature hashing, etc.
digest2int
digest2int(x, seed = 0L)
The digest2int function returns integer vector of the same length as input vector x.
x
An arbitrary character vector.
an integer for algorithm initial state. Function will produce different hashes for same input and different seed values.
