top_nodes: Displaying the Highest Cited Nodes

In agoutsmedt/networkflow: Functions For A Workflow To Manipulate Networks

Displaying the Highest Cited Nodes

Description

A simple function for keeping a number n of nodes with the highest chosen statistics value per communities and a number n of nodes with the highest chosen statistics value within the whole network. This is used to display only the most important nodes on your graph visualisation.

Usage

top_nodes(
  graph,
  ordering_column,
  top_n = 20,
  top_n_per_com = 1,
  biggest_community = FALSE,
  community_threshold = 0.01
)

Arguments

graph	A tidygraph object.
ordering_column	The name of the column with numeric values you want to use to select the most important nodes of your network. For instance, the column gathering the number of citations of each article of your dataframe.
top_n	The number of nodes with the highest chosen statistics value. For instance the number of highest cited nodes you want to display on the graph.
top_n_per_com	The number of highest cited nodes per community to display.
biggest_community	If true, you have the possibility to remove the smallest community, depending of the community_threshold you have set.
community_threshold	If biggest_community is true, the function only selects the nodes that belong to communities which represent at least x% of the total number of nodes. By default, the parameter is set to 1%.

Value

A data.table with a number n of nodes with the highest chosen statistics value per communities and a number n of nodes with the highest chosen statistics value within the whole network. Informations like coordinates (x,y) and community identifier are kept for using the data.table in a visualisation.
