influential (version 1.1.2)

h_index: H-index

Description

This function calculates the H-index of input vertices and works with both directed and undirected networks.

Usage

h_index(graph, vertices = V(graph), mode = "all")

Arguments

graph

A graph (network) of the igraph class.

vertices

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

mode

The mode of H-index depending on the directedness of the graph. If the graph is undirected, the mode "all" should be specified. Otherwise, for the calculation of H-index 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".

Value

A vector including the H-index of each vertex inputted.

Examples

# NOT RUN {
MyData <- coexpression.data
My_graph <- graph_from_data_frame(MyData)
GraphVertices <- V(My_graph)
h.index <- h_index(graph = My_graph, vertices = GraphVertices, mode = "all")
# }
