Fruchterman-Reingold Spring Layout — layout

Compute node positions using the Fruchterman-Reingold force-directed algorithm. Nodes connected by edges are attracted to each other while all nodes repel each other.

Usage

layout_spring(
  network,
  iterations = 500,
  cooling = 0.95,
  repulsion = 1,
  attraction = 1,
  seed = NULL,
  initial = NULL
)

Arguments

network: A CographNetwork object.
iterations: Number of iterations (default: 500).
cooling: Rate of temperature decrease (default: 0.95).
repulsion: Repulsion constant (default: 1).
attraction: Attraction constant (default: 1).
seed: Random seed for reproducibility.
initial: Optional initial coordinates (matrix or data frame).

Value

Data frame with x, y coordinates.

Examples

adj <- matrix(c(0, 1, 1, 0, 1, 0, 0, 1, 1, 0, 0, 1, 0, 1, 1, 0), nrow = 4)
net <- CographNetwork$new(adj)
coords <- layout_spring(net, seed = 42)
