Strength or weighted vertex degree — graph.strength • igraph

graph.strength() was renamed to strength() to create a more consistent API.

Usage

graph.strength(
  graph,
  vids = V(graph),
  mode = c("all", "out", "in", "total"),
  loops = TRUE,
  weights = NULL
)

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 weight edge attribute, then this is used by default. If the graph does not have a weight edge attribute and this argument is NULL, then a degree() is called. If this is NA, then no edge weights are used (even if the graph has a weight edge attribute).
