Look at function get.knn in package FNN: > library(FNN) > set.seed(42) > x <- rnorm(100, 50, 15) > y <- rnorm(100, 50, 15) > dat <- data.frame(x, y) > knns <- get.knn(dat, k=4) > str(knns) > knns.ndx <- data.frame(knns[["nn.index"]]) > head(knns.ndx)
knns is a list with two components, a matrix of indices to the nearest neighbors and a matrix of distances to the nearest neighbors. ---------------------------------------------- David L Carlson Associate Professor of Anthropology Texas A&M University College Station, TX 77843-4352 > -----Original Message----- > From: r-help-boun...@r-project.org [mailto:r-help-bounces@r- > project.org] On Behalf Of olemissrebs1123 > Sent: Tuesday, July 24, 2012 1:27 PM > To: r-help@r-project.org > Subject: Re: [R] Nearest Neighbors > > I don't see the "obvious" portion.
