WebR Documentation Approximate String Matching (Fuzzy Matching) Description Searches for approximate matches to pattern (the first argument) within the string x (the second argument) using the Levenshtein edit distance. Usage agrep (pattern, x, ignore.case = FALSE, value = FALSE, max.distance = 0.1) Arguments Details WebIn computer science, string-searching algorithms, sometimes called string-matching algorithms, are an important class of string algorithms that try to find a place where one or several strings ... and is therefore adaptable to fuzzy string searching. The bitap algorithm is an application of Baeza–Yates' approach. Index methods
