Exercise

# 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.

Instructions

**100 XP**

- 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`

.
