Count edges within a graph or edges between two non-overlapping graphs

1	count_edges(G, v1, v2 = NULL, edges = FALSE)

`G`	igraph which contains vertex identified by 'v1' and 'v2'.
`v1`	vector of vertex identifiers.
`v2`	vector of vertex identifiers. 'NULL' by default, but when a second vector is supplied, the fuction will return the number of edges connecting the two subgraphs indicated by the vertex lists.
`edges`	logical. If TRUE, the edges rather than the count will be returned as a data.frame with two columns named "vi" and "vj".
