Oppgave
Swipe to start coding
You have already created a factor vector, grades_f, which assigns each numeric grade into one of five categories ('F', 'D', 'C', 'B', 'A'). Your goal is to:
- Call the
summary()function on yourgrades_fvariable to output the number of occurrences of each factor grade. - Divide those counts by the total number of grades, computed by calling
length()function ongrades_fvariable, to obtain the relative frequency of each grade.
