Exercise

Who Was the Champion?

The dplyr package has been loaded for you, as has the solution to the previous question. The arrange() function in dplyr allows you to re-order a vector based on a trait.

In the previous exercise, you rated the teams at the end of the 2017 WNBA season using the solution to a matrix-vector equation.

Using the the syntax

arrange(r, -Rating)

we can see which team was the best in the WNBA in 2017 (using the negative ("-") sign in front of the ordering variable ("Rating") puts the values in descending order, as opposes to ascending order if just "Rating" is used).

Which team was the best?
