can you create the code for R that runs the louvain algorithm on a network of 2 0 nodes and is undirected where it visualises
can you create the code for R that runs the louvain algorithm on a network of nodes and is undirected where it visualisesplots each step modularity optimization and community aggregation I have used the following code and works apart from it doesnt have edges between the nodes in the community aggregation graph: # Load necessary library
libraryigraph
# Define the edges of your network adjust as needed
edges c
# Create the initial graph ensure it's undirected
graph graphedges directed FALSE
# Initial plot
plotgraph main "Original Network"
# Step : Modularity Optimization
louvainpartition clusterlouvaingraph
# Visualize the modularity optimization
plotlouvainpartition, graph, main "Modularity Optimization"
# Step : Community Aggregation
while TRUE
