ClusterStrings: Cluster similar strings

In ms609/TreeSearch: Phylogenetic Analysis with Discrete Character Data

Cluster similar strings

Description

Calculate string similarity using the Levenshtein distance and return clusters of similar strings.

Usage

ClusterStrings(x, maxCluster = 12)

Arguments

x	Character vector.
maxCluster	Integer specifying maximum number of clusters to consider.

Value

NameClusters() returns an integer assigning each element of x to a cluster, with an attribute med specifying the median string in each cluster, and silhouette reporting the silhouette coefficient of the optimal clustering. Coefficients < 0.5 indicate weak structure, and no clusters are returned. If the number of unique elements of x is less than maxCluster, all occurrences of each entry are assigned to an individual cluster.
