Changed name of parameters "nds.df" -> "nodes" and "eds.df" -> "edges".
Removed shw option. Now parameters "nodes" and "edges" are NULL by default. If they are not set, then the corresponding concept is not plotted. This also allows to plot both if both are set.
eds.color is now a pair for each type of edges. Previously, the colors were hardcoded.
The correction of the y-coordinates is now done with a change of signe (-) instead of extracting the absolute value. This is more in agreement with the logic of the corrected effect.
Changed use:
