Readings

Skim the readings before or after class to get the big picture and prep for quizzes and assignments:

• Chapter 20 “Vectors” in “R for Data Science” 1st Edition. I assigned the 1st Edition because I find it a bit clearer on this topic than the 2nd Edition, but you might want to take a look also at Chapter 12 “Logical Vectors” and Chapter 13 “Numbers” of the 2nd Edition and decide what you prefer. Either works!
• Chapter 27 “A field guide to base R” in “R for Data Science” 2nd Edition.
