leven: Edit distance for Dialectometry

In dialectR: Doing Dialectometry in R

Description

An edit distance for use in Dialectometry. Allows for normalization by dividing alignment length, and for accommodating multiple responses with Bilbao distance, as proposed by Aurrekoetxea et al (2020).

Usage

leven(vec1, vec2, alignment_normalization = FALSE, delim = NULL)

Arguments

vec1	A vector of words.
vec2	A vector of words to be compared against.
alignment_normalization	A logical value, indicating whether or not the difference scores are to be normalized by alignment length.
delim	An optional delimiter, in situations where multiple responses exist in the data.

Value

A number indicating the number of operations to transform a string to the other, which optionally may undergo length normalization.
