Creating Graph And Keeping Main Component With Tidygraph From Edges And Nodes

This function is deprecated and will be replaced by networkflow::extract_main_component(). This function which i) creates a tidygraph graph using tbl_graph(); ii) keeps the main components of the graph, using main_components(); and iii) warns the user if the first biggest component removed is too large.

Usage

tbl_main_component(
  edges,
  nodes,
  nb_components = 1,
  threshold_alert = 0.05,
  ...
)

Arguments

edges: A dataframe with a list of links between nodes, under the columns "from" and "to". The two columns should be in character format.
nodes: A dataframe with a list of nodes. The first column will be used as the identifying column. Be careful to avoid doublons in the first column. The first column should be in character format.
nb_components: By default, the function takes the main component of the graph (nb_components = 1). However it is possible to take as many components as you wish Component 1 is the largest one, component 2 is the second one, etc.
threshold_alert: If the biggest component after the last one selection (by default, nb_component = 1) gathers more than x% (by default, 5%) of the total number of nodes, the function triggers a warning to inform the user that he has removed a big component of the network.
...: Any parameter of the tbl_graph() function. Edges are directed by default. Coupling or co-citation network are undirected networks.

Value

A tidygraph object with a list of nodes and a list of edges.

Details

The function will automatically rename the first column of nodes as "Id".
