Factor summary
As any good bond investor would do, you would like to keep track of how many bonds you are holding of each credit rating. A way to present a table of the counts of each bond credit rating would be great! Luckily for you, the summary() function for factors can help you with that.
The character vector credit_rating and the factor credit_factor are both in your workspace.
