Similarity measures of two vertices (Dice)

Please use similarity() with method = "dice" instead.

similarity.dice(
  graph,
  vids = V(graph),
  mode = c("all", "out", "in", "total"),
  loops = FALSE
)

`graph`	The input graph.
`vids`	The vertex ids for which the similarity is calculated.
`mode`	The type of neighboring vertices to use for the calculation, possible values: ‘`out`’, ‘`⁠in⁠`’, ‘`all`’.
`loops`	Whether to include vertices themselves in the neighbor sets.
