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.

练习说明

Inspect the first rows of the edgeList dataframe using the head() function.
Create an igraph object called network with the edgeList dataframe using the graph_from_dataframe() function. Use the logical directed argument to specify that the network is undirected.
Inspect the igraph object you created by calling its name.
