In valenlab/amplican: Automated analysis of CRISPR experiments

Generate all combinations along string exchanging m characters at a time with dictionary letters.

Description

Generate all combinations along string seq swapping m characters at a time with letters defined in dictionary letters. Allows, for instance, to create a list of possible primers with two mismatches.

Usage

comb_along(seq, m = 2, letters = c("A", "C", "T", "G"))

Arguments

seq	(character) input character to permutate
m	(integer) number of elements to permutate at each step
letters	(character vector) dictionary source for combinations of elements

Value

(character vector) all unique combinations of permutated string

Examples

comb_along("AC")
comb_along("AAA", 1)
comb_along("AAA")
comb_along("AAA", 3)
comb_along("AAAAAAAAAA")
