Exercise

Explore the dataset

In this first exercise, you will explore the Madrid train bombing dataset. This dataset consists of two parts: the nodes (also called vertices), which refer to people, and the ties (also called edges) which refer to the relationships between these people. You will use the package readr to read the nodes and ties from CSV files into variables in R. For your convenience, the package readr is already loaded into the workspace.
