Returns a graph object with vertices that meet certain criteria. By default, only vertices that meet these criteria for all input graphs will be retained.
Graph objects or lists of graph objects
Character string specifying an equation (logical condition) for the vertices to subset
Logical indicating whether to keep all vertices that
meet the criteria in at least 1 input graph. Default:
If no vertices meet criteria for all input graphs, then an
graph object with 0 vertices is returned. If
this is essentially performing a union of vertex sets that meet the
criteria. In any case, the return graph will have 0 edges.
