seqhash: Individually hash biological sequences

In brendanf/tzara: Cluster long amplicons using dada2 denoising on variable regions

Description

Individually hash biological sequences

Usage

seqhash(seq, algo = "xxhash32", len = NA, preserve_na = TRUE)

## S3 method for class 'character'
seqhash(seq, algo = "xxhash32", len = NA, preserve_na = TRUE)

## S3 method for class 'XStringSet'
seqhash(seq, algo = "xxhash32", len = NA, preserve_na = TRUE)

Arguments

seq	(character or XStringSet-class) the sequences to hash.
algo	(character) a hash algorithm supported by digest. default: "xxhash32"
len	(integer) number of characters to keep from each hash string. NA (the default) to keep all characters.
preserve_na	(logical) If TRUE, NA values in seq are preserved as NA in the output. If FALSE, then NA is passed to digest, which results in a valid hash.

Value

a character vector of the same length as seq, with the hashed sequences.
