ForceAtlas2 on a pre-computed graph — rs_forceatlas2_from

Leverages the ForceAtlas2 implementation in manifolds-rs and lays out a caller-supplied undirected graph. Each edge is passed once; the Rust side adds the reverse direction.

Usage

rs_forceatlas2_from_graph(
  from,
  to,
  weight,
  n,
  init,
  fa2_params,
  seed,
  use_high_precision,
  verbose
)

Arguments

from: Integer vector. 1-based source vertex of each edge.
to: Integer vector. 1-based target vertex of each edge.
weight: Numeric vector. Weight of each edge.
n: Integer. Number of vertices.
init: Optional numerical matrix of dimensions n x 2. The initial layout. If NULL, a random layout is used.
fa2_params: Named list. List that contains the ForceAtlas2 optimisation parameters.
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.

Value

The ForceAtlas2 embedding, n x 2.
