We typically aren't just working with scalars $($single values$)$ or a handful of vectors. Usually a statistician, analyst, or data scientist will be working with a table $($or many tables$)$ filled with raw data. We'll call these tables data frames, and you can see the first six rows of the diamonds data frame $($from our first tutorial$)$ below.

head $($diamonds$)$

We can call a column of a dataframe in several different ways. For example, diamonds $cut, diamonds $[,$ "cut"$],$ and diamonds $[,3]$ all access the cut column of the diamonds data frame but the first method returns a vector of values while the two methods making use of brackets return a data frame. Alter the code below so that you access the column as a vector instead of the cut column as a vector.
