Loading data into R

In the previous video, we saw how to load the hsb2 dataset into R using the data() function and how to preview its contents with str().

In this exercise, we'll practice on another dataset, email50, which contains a subset of incoming emails for the first three months of 2012 for a single email account. We'll examine the structure of this dataset and determine the number of rows (observations) and columns (variables).
