Tricks of fct_relevel()

In the previous exercise, the name of each level had to be written out to explicitly reorder the factor. But sometimes you have many levels and only need to move one. Instead of writing out all the levels, you can use some helper arguments in fct_relevel() to save you some typing. Let's try some of them out on the variable FormalEducation in multiple_choice_responses; view the levels of the multiple_choice_responses$FormalEducation in the console to get started.

  • In three mutate calls, change FormalEducation in the following ways:
    • Move "I did not complete any formal education past high school" and "Some college/university study without earning a bachelor's degree" to the front.
    • Move "I prefer not to answer" to be the last level.
    • Move "Doctoral degree" to be the sixth level (after the fifth level).
