R Introduction: Part I

# Counting Values

If you're looking to count the occurrences of each value within a vector, the `summary()` function is exactly what you need.

To tally the frequency of each level within a factor, use the `summary()` function with the factor as its argument. This will list the occurrences for each level that the factor can take. For instance:

Remember, the sequence of the levels reported by `summary()` corresponds to the order defined when you used the `factor()` function. If no order is defined, it defaults to numerical or alphabetical order.

Завдання

For the grades data mentioned earlier, compute the frequency of each grade within the `grades_f` factor.
