damerau_levenshtein_distance: Damerau-Levenshtein Distance

In RapidFuzz: String Similarity Computation Using 'RapidFuzz'

Damerau-Levenshtein Distance

Description

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")
damerau_levenshtein_distance("abcdef", "abcfde", score_cutoff = 3)
