Project an affiliation network onto its actors

These functions use bipartite_projection to compute the projections of an affiliation network onto the actor or event nodes.

mode_projection(graph, mode = 1, name = "name")

actor_projection(graph, ...)

event_projection(graph, ...)

actor.projection(graph, ...)

event.projection(graph, ...)

Arguments

graph	An affiliation network.
mode	Numeric or character; whether to project onto actors (1 or "actors") or onto events (2 or "events").
name	Character; the attribute of the actor or event nodes in graph to use as names for the nodes in the projection. If NA, node IDs are converted to characters and used. If NULL, no names are assigned.
...	Arguments passed to mode_projection.

vcount(proj) == tab[1]
#> FALSE 
#>  TRUE 
proj <- event_projection(chicago1960s)
vcount(proj) == tab[2]
