##### Convert a graph to an adjacency matrix or an edge list

Sometimes it is useful to have a standard representation of a graph, like an adjacency matrix or an edge list.

Keywords
graphs
##### Usage
get.adjacency(graph, type="both")
get.edgelist(graph)
##### Arguments
graph
The graph to convert.
type
Gives how to create the adjacency matrix for undirected graphs. It is ignored for directed graphs. Possible values: upper: the upper right triangle of the matrix is used, lower: the lower left triangle of the matrix i
##### Details

get.adjacency returns the adjacency matrix of a graph.

get.edgelist returns the list of edges in a graph.

##### Value

• A vcount(graph) by vcount(graph) numeric matrix for get.adjacency. (This can be huge!)

A ecount(graph) by 2 numeric matrix for get.edgelist.

graph.adjacency, read.graph
