This function calculates the Hubness score of the desired nodes from a graph. Hubness score reflects the power of each node in its surrounding environment and is one of the major components of the IVI.

hubness.score(
  graph,
  vertices = V(graph),
  directed = FALSE,
  mode = "all",
  loops = TRUE,
  scaled = TRUE
)

Arguments

graph

A graph (network) of the igraph class.

vertices

A vector of desired vertices, which could be obtained by the V function.

directed

Logical scalar, whether to directed graph is analyzed. This argument is ignored for undirected graphs.

mode

The mode of Hubness score depending on the directedness of the graph. If the graph is undirected, the mode "all" should be specified. Otherwise, for the calculation of Hubness score based on incoming connections select "in" and for the outgoing connections select "out". Also, if all of the connections are desired, specify the "all" mode. Default mode is set to "all".

loops

Logical; whether the loop edges are also counted.

scaled

Logical; whether the end result should be 1-100 range normalized or not (default is TRUE).

Value

A numeric vector with the Hubness scores.

Examples

if (FALSE) {
MyData <- coexpression.data
My_graph <- graph_from_data_frame(MyData)
GraphVertices <- V(My_graph)
Hubness.score <- hubness.score(graph = My_graph, vertices = GraphVertices,
                               directed = FALSE, mode = "all",
                               loops = TRUE, scaled = TRUE)
