Centroid Sequences

Description

Find centroid sequences among a collection of sequences.

Usage

sdists.center(x, d = NULL, method = "ow", weight = c(1, 0, 2),
              exclude = c(NA, NaN, Inf, -Inf), FUN = NULL, ...,
              unique = FALSE)

Arguments

x a list (of vectors) of a vector of character.
d a matrix or an object of class dist.
method argument to sdists.
weight argument to sdists.
exclude argument to sdists.
FUN a function to rank distances.
... additional arguments to FUN.
unique a logical specifying whether to return a unique set of sequences.

Details

This function provides a wrapper to computing the distances among the sequences in x, unless d is supplied, and the subsequent selection of a set of centroid sequences with minimum sum of distances to any other sequence.

Value

A subset of x.
