Exercises 7 - Creating Variables

We’ll continue to work on the same .Rmd file from the previous exercise.

7.1 Create a New Variable

1. Write a brief note using Markdown syntax that mentions we’ll be investigating the name George in more detail and that we’ll be creating a new variable that represents the change year to year.

2. Use the BabyNamesFull data object and filter the data to only contain observations where sex is M and the name is George.

3. Create a new variable using mutate() that is the difference from year to year for the count variable. This can be done using the lag() function via count-lag(count). Call this variable diff.
