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.
COGRAPH_SCALEA list with the following elements:
Scale factor applied to node_size parameter
Default node size when not specified
Default label size (cex multiplier)
Whether label size is coupled to node size
Base edge width
Edge width scale factor
Default edge width
Scale factor for arrow sizes
Default arrow size
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)
