ForceAtlas2 implementation — rs_forceatlas2_from

Leverages the ForceAtlas2 implementation in manifolds-rs. This version uses a pre-computed kNN graph, please see new_nearest_neighbour().

Usage

rs_forceatlas2_from_knn(
  embd,
  knn_data,
  k,
  fa2_params,
  seed,
  use_high_precision,
  verbose
)

embd: Numerical matrix. The data to use to generate the embeddings. Should be of dimensions samples x features.
knn_data: NearestNeighbours class from R.
k: Integer. Number of nearest neighbours to consider.
fa2_params: Named list. List that contains all of the key parameters for the graph generation and ForceAtlas2 optimisation.
seed: Integer. Seed for reproducibility.
use_high_precision: Optional logical. Controls fp32 vs fp64. If NULL will use sensible default thresholding.
verbose: Integer. If 0L -> silent or 1L for normal verbosity; 2L for detailed verbosity.
