Compute the Levenshtein-Damerau distance between two character strings (the minimal number of insertions, deletions replacements, or transpositions required to transform one string into the other)
Usage
levenshtein.damerau.distance(xsource, targets)
Arguments
xsource
A character string to compute the Levenshtein-Damerau distance from.
targets
A list of words to compute the Levenshtein-Damerau distance to. Must be of type character, or convertible to type character with as.character.
Value
An integer vector containing Restricted Levenshtein-Damerau distances, with names corresponding to targets.
Details
The distance computation is performed by stringdist with method="osa". Note that this function computes the restricted Levenshtein-Damerau distance instead of the unrestricted version.
