Create a network from an edgelist
In this exercise, you will create a network from an edgelist.
You will create an igraph object from data stored in an edgelist using the function graph_from_data_frame(). The data is a social network of customers and each row of the edgeList dataframe represents an edge in the network. The edges in this network are undirected and have weight 1. This is indicated by the directed argument of the function, which is logical so the value FALSE means that the network is undirected.
The igraph package has been loaded for you.
