R Documentation

Find Nearest Neighbor Distances

Description

Given one (or two) multivariate data sets, a difference method, and k neighbors to search for, neighbors finds the k points in the data set (or the second data set) that are closest to each point in the data set (or the first data set)

Usage

neighbors(X, Y = NULL, method = "euclidean", n.neighbors = 1, init.info = NULL)

Arguments

X	a matrix of numeric values
Y	an optional second matrix that must have the same number of columns as X
method	one of the method choices from diss
n.neighbors	an integer between 1 and nrow(X) (or nrow(Y), if it is not null)
init.info	some difference methods require additional information. see diss

Value

returns an nrow(X) by n.neighbors matrix of distances
