calcKNNgraph_euclidean: Calculate k Nearest Neighbors from Euclidean distance metric

In yinscapital/yolo-caleblareau-reference: You Only Lookup One (small part of an otherwise large matrix)

Description

Each distance metric has its own function for speed/efficiency This takes a sample X feature matrix and returns a matrix of k nearest neighbors. This is the one for Euclidean.

Usage

calcKNNgraph_euclidean(x, k = 1L)

Arguments

x	An m x n numeric matrix
k	The number of nearest neighbors to return per sample

Value

An m x k matrix of indicies 1...k of the nearest neighbors for the specified row based on Euclidean distance.
