Average nearest neighbor degree

Source: R/structural.properties.R
graph.knn.Rd

[Deprecated]

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

Usage

graph.knn(
  graph,
  vids = V(graph),
  mode = c("all", "out", "in", "total"),
  neighbor.degree.mode = c("all", "out", "in", "total"),
  weights = NULL
)

Arguments

graph

The input graph. It may be directed.

vids

The vertices for which the calculation is performed. Normally it includes all vertices. Note, that if not all vertices are given here, then both ‘knn’ and ‘knnk’ will be calculated based on the given vertices only.

mode

Character constant to indicate the type of neighbors to consider in directed graphs. out considers out-neighbors, in considers in-neighbors and all ignores edge directions.

neighbor.degree.mode

The type of degree to average in directed graphs. out averages out-degrees, in averages in-degrees and all ignores edge directions for the degree calculation.

weights

Weight vector. If the graph has a weight edge attribute, then this is used by default. If this argument is given, then vertex strength (see strength()) is used instead of vertex degree. But note that knnk is still given in the function of the normal vertex degree. Weights are are used to calculate a weighted degree (also called strength()) instead of the degree.
