Generates the kNN graph with additional distances

This function is a wrapper over the Rust-based generation of the approximate nearest neighbours.

Usage

rs_sc_knn_w_dist(embd, knn_params, verbose, seed)

Arguments

embd

Numerical matrix. The embedding matrix to use to generate the kNN graph.

knn_params

List. The kNN parameters defined by params_sc_neighbours().

verbose

Boolean. Controls verbosity of the function and returns how long certain operations took.

seed

Integer. Seed for reproducibility purposes.

Value

A list with:

• indices - An integer matrix representing the indices of the approximate nearest neighbours.

• dist - An numerical matrix representing the distances to the nearest neighbours.

• dist_metric - String representing the used distance metric.
