Details

The attrs slot is a named list, where the names correspond to attributes and the values in the list correspond to the value for that element's attribute.

The subG slot describes which subgraph this edge is a part of. A value of 0 implies that the edge is not a member of any subgraph.

Objects can be created by calls of the form new("pEdge", ...).

from:
Object of class "character": The name of the node on the tail of this edge.

attrs:
Object of class "list": A list of attributes specific to this edge.
subG:
Object of class "integer": Which subgraph this edge is a part of.
