logical. Whether to warn if new vertices are created.
Value
Returns a hypergraph (or graph) as appropriate.
Details
The edges can be indices or edge names. This is different than the graph
call -- see the igraph package help for that.
If edges is NULL, or missing,
hypergraph.add.edges adds a single empty hyper-edge to the hypergraph.
add.hyperedges is an alias for hypergraph.add.edges.
# NOT RUN { h <- hypergraph_from_edgelist(list(1:4,1:2,c(2,3,5),c(3,5:7)))
h1 <- hypergraph.add.vertices(h,1,"8")
h2 <- hypergraph.add.edges(h,list(c(1,5,8),7:9))
# }
