Question 2: We would like to plot the death rate for each disease over time. To do so, we must create a table with one column for each cause and one row for each year. Create a table called causes_for_plotting. It should have one column called Year, and then a column with age-adjusted death rates for each of the causes you found in Question 1. There should be as many of these columns in causes_for_plotting as there are causes in Question 1. Hint: Use pivot, and think about how the elem function might be useful in getting the Age Adjusted Death Rate for each cause and year combination
