Add actor and event nodes

These functions add actor and event nodes (as desired) to a graph while maintaining its (temporal) affiliation network structure.

add_modes(graph, mode = 1, nv, ..., attr = list(), affiliations = NULL)

add_actors(graph, nv, ..., attr = list(), events = NULL)

add_events(graph, nv, ..., attr = list(), actors = NULL)

Arguments

graph	An affiliation network.
mode	Numeric or character; whether to project onto actors (1 or "actors") or onto events (2 or "events").
nv, ..., attr	Arguments passed to add_vertices. Events added to a dynamic affiliation network should be given time attributes.
affiliations	A vector, or list of length nv of vectors, of nodes in graph of mode not mode, to be linked to the new node(s).
events	A vector, or list of length nv of vectors, of event nodes in graph, to be linked to the new actor(s).
actors	A vector, or list of length nv of vectors, of actor nodes in graph, to be linked to the new event(s).

Examples

data(women_clique)
plot(prettify_an(add_actors(women_clique, nv = 1, events = c(7, 9))))
data(women_group)
plot(prettify_an(women_group))

  ),
  dynamic_triad_closure(
    add_events(women_group, nv = 1, actors = actor_names, time = 367),
    type = "local"
