Two vertices are cocited if there is another vertex citing both of them.
cocitation simply counts how many types two vertices are cocited. The
bibliographic coupling of two vertices is the number of other vertices they
both cite, bibcoupling calculates this.
cocitation(graph, v = V(graph))The graph object to analyze
Vertex sequence or numeric vector, the vertex ids for which the cocitation or bibliographic coupling values we want to calculate. The default is all vertices.
A numeric matrix with length(v) lines and
vcount(graph) columns. Element (i,j) contains the cocitation
or bibliographic coupling for vertices v[i] and j.
cocitation calculates the cocitation counts for the vertices in the
v argument and all vertices in the graph.
bibcoupling calculates the bibliographic coupling for vertices in
v and all vertices in the graph.
Calculating the cocitation or bibliographic coupling for only one vertex costs the same amount of computation as for all vertices. This might change in the future.
