community_names: Automatically Attributing Names to Communities

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

Automatically Attributing Names to Communities

Description

A function to give to a community the name of its node with the highest chosen measure. It also gives the edges the name of their community. If the edge connects nodes from different community, name will be NA.

The function takes into account the parameters chosen for the leiden_improved() function. If you have chosen 2 or 3 levels of resolution, it repeats the same process for the second and third resolution. In other words, for 3 levels of resolution, you will have the names of the communities for the first value of the Leiden resolution, but also the names for the second and third values.

Usage

community_names(
  graph,
  ordering_column,
  naming = "Label",
  community_column = "Com_ID"
)

Arguments

graph	A tidygraph object.
ordering_column	Enter the name of the column you want to be used to choose the community name. For instance, if you choose Degree, the function takes the value of the naming column of the node with the highest degree in the community to name the community. You can use other measure than network centrality measures: for instance, if nodes are articles, you can use the number of citations of articles.
naming	Enter the name of the column you want to be used for naming the community. The function takes the node with the highest centrality_measure chosen, and use the node value in the naming column to title the community. For instance, if nodes are individuals and if you have a column called surname, you can use this column.
community_column	The name of your community identifiers column.

Details

The attribute of nodes and edges with the names of the communities is called Community_name. It is formed by the identifier of the community (in the Com_ID column) and by the naming value.

If you have entered a second and a third resolutions values in the leiden_improved() function, you will have two supplementary columns: Community_2_name and Community_3_name.

Value

The same graph object but with a column Community_name, as well as Community_2_name and Community_3_name if you have run the leiden_workflow() function for more than one resolution.
