Degree and degree distribution of the vertices

The degree of a vertex is its most basic structural property, the number of its adjacent edges.

Keywords
graphs
Usage
degree(graph, v=igraph.vs.all(graph), mode = "total", loops = TRUE) 
degree.distribution(graph, cumulative = FALSE, ...)
Arguments
graph
The graph to analyze.
v
The ids of vertices of which the degree will be calculated.
mode
Character string, out for out-degree, in for in-degree or total for the sum of the two. For undirected graphs this argument is ignored.
loops
Logical; whether the loop edges are also counted.
cumulative
Logical; whether the cumulative degree distribution is to be calculated.
...
Additional arguments to pass to degree, eg. mode is useful but also v and loops make sense.
Value

  • For degree a numeric vector of the same length as argument v.

    For degree.distribution a numeric vector of the same length as the maximum degree plus one. The first element is the relative frequency zero degree vertices, the second vertices with degree one, etc.
