Calculate the Damerau-Levenshtein distance between two strings.
Computes the Damerau-Levenshtein distance, which is an edit distance allowing transpositions in addition
to substitutions, insertions, and deletions.
Usage
damerau_levenshtein_distance(s1, s2, score_cutoff = NULL)
Arguments
- s1
A string. The first input string.
- s2
A string. The second input string.
- score_cutoff
An optional maximum threshold for the distance. Defaults to the largest
integer value in R (`.Machine$integer.max`).
Value
The Damerau-Levenshtein distance as an integer.
Examples
damerau_levenshtein_distance("abcdef", "abcfde")
#> [1] 2
damerau_levenshtein_distance("abcdef", "abcfde", score_cutoff = 3)
#> [1] 2
