Create a bipartite graph
A bipartite graph has two kinds of vertices and connections are only allowed between different kinds.
graph.bipartite(types, edges, directed=FALSE)
- A vector giving the vertex types. It will be coerced into boolean. The length of the vector gives the number of vertices in the graph.
- A vector giving the edges of the graph, the same way as
for the regular
graphfunction. It is checked that the edges indeed connect vertices of different kind, accoding to the supplied
- Whether to create a directed graph, boolean constant. Note that by default undirected graphs are created, as this is more common for bipartite graphs.
Bipartite graphs have a
FALSE for the vertices of the first
TRUE for vertices of the second kind.
graph.bipartite basically does three things. First it checks
edges vector against the vertex
types. Then it
creates a graph using the
edges vector and finally it adds the
types vector as a vertex attribute called
- A bipartite igraph graph. In other words, an igraph graph that has a
- Bipartite graph
- Two-mode network
graph to create one-mode networks
g <- graph.bipartite( rep(0:1,length=10), c(0:9)) print(g, v=TRUE)
