pEdge-class {Rgraphviz} | R Documentation |
This class is used to represent all necessary information to plot an edge in Graphviz
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", ...)
.
