Counting types of edges

In this exercise, you will count the number of each edge type using the edgeType column in the edgeList dataframe. In the edgeList$edgeType column, there are three different values:

0 for edges that connect two non-churn nodes.
1 for edges that connect a non-churn and a churn node. These are called mixed or cross-label edges.
2 for edges that connect two churn nodes.

Instruções do exercício

Count the number of churn edges by conditioning on edgeList$edgeType. Assign the value to ChurnEdges.
Count the number of non-churn edges by conditioning on edgeList$edgeType. Assign the value to NonChurnEdges.
Count the number of mixed edges by conditioning on edgeList$edgeType. Assign the value to MixedEdges.
Count the total number of edges and assign the value to edges.
