Build kNN graph from distance (used in "build_knn_graph")

Description

Build kNN graph from distance (used in "build_knn_graph")

Usage

knn_graph_from_dist(D, k = 5, return_neighbors_order = TRUE, mode = "all")

Arguments

D	dist matrix or dist object (preferentially)
k	kNN parameter
return_neighbors_order	whether return order of neighbors (not available for nn2 option)
mode	mode of graph_from_adj_list ('all' – undirected graph, 'out' – directed graph)

Value

a list with components

• graph.knn - igraph object

• order - Nxk matrix with indices of k nearest neighbors ordered by relevance (from 1st to k-th)
