cograph (version 1.5.2)

layout_oval: Oval Layout

Description

Arrange nodes evenly spaced around an ellipse. This creates an oval-shaped network layout that is wider than it is tall (or vice versa depending on ratio).

Usage

layout_oval(
  network,
  ratio = 1.5,
  order = NULL,
  start_angle = pi/2,
  clockwise = TRUE,
  rotation = 0
)

Value

Data frame with x, y coordinates.

Arguments

network

A CographNetwork object.

ratio

Aspect ratio (width/height). Values > 1 create horizontal ovals, values < 1 create vertical ovals. Default 1.5.

order

Optional vector specifying node order (indices or labels).

start_angle

Starting angle in radians (default: pi/2 for top).

clockwise

Logical. Arrange nodes clockwise? Default TRUE.

rotation

Rotation angle in radians to tilt the entire oval. Default 0.

Examples

adj <- matrix(c(0, 1, 1, 1, 0, 1, 1, 1, 0), nrow = 3)
net <- CographNetwork$new(adj)
coords <- layout_oval(net, ratio = 1.5)
