In cograph: Analysis and Visualization of Complex Networks

qgraph Cent2Edge (EXACT - critical formula)

Description

Calculates the point on node boundary where an edge should connect. This is qgraph's exact formula for positioning arrows and edge endpoints.

Usage

qgraph_cent2edge(x, y, cex, offset = 0, angle, plot_info = NULL)

Arguments

x	Node center x coordinate.
y	Node center y coordinate.
cex	Node size (vsize value, not yet scaled).
offset	Additional offset distance.
angle	Angle from node center to target point (radians).
plot_info	Plot dimension info from qgraph_plot_info(). NULL to auto-compute.

Value

List with x, y coordinates on node boundary.
