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.
