COGRAPH_SCALE: cograph Scaling Constants

In cograph: Analysis and Visualization of Complex Networks

cograph Scaling Constants

Description

Central location for all scaling factors used in splot() and soplot(). These constants are calibrated to produce similar visual output to qgraph when using equivalent parameter values.

Usage

COGRAPH_SCALE

Format

A list with the following elements:

node_factor

Scale factor applied to node_size parameter

node_default

Default node size when not specified

label_default

Default label size (cex multiplier)

label_coupled

Whether label size is coupled to node size

edge_base

Base edge width

edge_scale

Edge width scale factor

edge_default

Default edge width

edge_width_range

Default output range for scaled edge widths

edge_scale_mode

Default edge scaling mode

edge_cut_quantile

Default cut quantile used by callers

edge_width_default

Default edge width when weights are unavailable

arrow_factor

Scale factor for arrow sizes

arrow_default

Default arrow size

soplot_node_factor

Node-size factor for soplot NPC coordinates

tna_edge_color

Default TNA edge color

Details

The default scaling mode uses values calibrated to match qgraph visual appearance:

• node_size = 6 in cograph should look similar to vsize = 6 in qgraph

• label_size = 1 uses cex-style multiplier (independent of node size)

• arrow_size = 1 produces consistent arrows between splot and soplot

Legacy mode preserves the original cograph v1.x behavior where:

• Node sizes used a 0.04 scale factor

• Label sizes were coupled to node size (vsize * 8)

• Arrow sizes differed between splot (0.03) and soplot (0.015)
