## Answer Report
Finally, let's generate a report that summarizes your answers to this evaluation.
Answers are written to a file that looks like this: `question_submission-{CURRENT TIME}.csv`. They're also saved in R Studio's global environment as a variable called `df`. Run the below code chunk to see what `df` looks like.
Answers are written to a file that looks like this: `question_submission-{CURRENT TIME}.csv`.
Take note of this csv file: this is what you will submit to Canvas.
