Make getSymbols() return the data it retrieves

In the last exercise, getSymbols() automatically created an object named like the symbol you provided. This exercise will teach you to make getSymbols() return the data, so you can assign the output yourself.

There are two arguments that will make getSymbols() return the data:

Set auto.assign = FALSE.
Set env = NULL.

The two methods are functionally equivalent, but auto.assign = FALSE describes the behavior better. Use it because you will be more likely to remember what auto.assign = FALSE means in the future.
