The tibbles chapter, 7

1. Create a small tibble manually
2. Do exercises 1,2,4,5,6 from this chapter. I have no idea what 3 is about, so it can't be important, right???

The readr chapter, 8

In the first set of chapter questions, do questions 1, 2, and 4.

If you have time, do 5.

The tidy chapter, 9

Note: there is an annoyance in this chapter. The data sets, table1, etc., may have to be referred to as tidyr::table1.

Do the following:

1. Exercise 3 in the first set of exercises.
2. Exercise 2 in the second set of exercises

The "database-like stuff" with dplyr chapter, 10

1. Exercise 1 in second set of exercises
2. Exercise 2 in the third set of exercises

Note: this chapter is worth studying in detail!! Join operations are extremely common. We just don't have time to have you do all the problems.
