bookChallenge: Grades Summary

Task

Swipe to start coding

You have a factor vector, grades_f, which assigns each numeric grade into one of five categories ('F', 'D', 'C', 'B', 'A'). Your goal is to:

  1. Use the summary() function on grades_f to display the number of occurrences of each grade.
  2. Compute the relative frequency of each grade by dividing the counts from the previous step by the total number of grades. To find the total, call the length() function on grades_f.
