draw_self_loop_base: Draw Self-Loop Edge (qgraph-style)

Description

Renders a self-loop (edge from node to itself) using a teardrop/circular loop shape similar to qgraph.

Usage

draw_self_loop_base(
  x,
  y,
  node_size,
  col = "gray50",
  lwd = 1,
  lty = 1,
  rotation = pi/2,
  arrow = TRUE,
  asize = 0.02,
  arrow_angle = pi/6
)

Arguments

x, y

Node center coordinates.

node_size

Node radius.

col

Loop color.

lwd

Line width.

lty

Line type.

rotation

Angle in radians for loop direction (default: pi/2 = top).

arrow

Logical: draw arrow?

asize

Arrow size.

arrow_angle

Arrow head angle in radians. Default pi/6 (30 degrees).
