strength | R Documentation |
Summing up the edge weights of the adjacent edges for each vertex.

)
graph |
The input graph. |
vids |
The vertices for which the strength will be calculated. |
mode |
Character string, “out” for out-degree, “in” for in-degree or “all” for the sum of the two. For undirected graphs this argument is ignored. |
loops |
Logical; whether the loop edges are also counted. |
weights |
Weight vector. If the graph has a |
A numeric vector giving the strength of the vertices.
