emst_mlpack: Euclidean Minimum Spanning Tree

Description

Provides access to the implementation of the Dual-Tree Boruvka algorithm from the mlpack package (if available). It is based on kd-trees and is fast for (very) low-dimensional Euclidean spaces. For higher dimensional spaces (say, over 5 features) or other metrics, use the parallelised Prim-like algorithm implemented in mst().

Usage

emst_mlpack(X, leaf_size = 1, naive = FALSE, verbose = FALSE)

Arguments

X

a numeric matrix (or an object coercible to one, e.g., a data frame with numeric-like columns)

leaf_size

size of leaves in the kd-tree, controls the trade-off between speed and memory consumption

naive

logical; whether to use the naive, quadratic-time algorithm

verbose

logical; whether to print diagnostic messages

Value

An object of class mst, see mst() for details.
