Counting Part 2

While the group_by() and summarize() functions are great for summarizing this information, a Padawan youngling has pointed out that the information is not ordered.

🙄 Rolling your eyes, you tell them that you know this! We just need to use another function in order to arrange this data. It’s time for you to demostrate this. J-327D notes that journalists are typically interested in the most of something, so to make sure to sort in descending order.

Sorting a dataframe

Change the counted list to show the species with the most characters are the top

Solution

starwars |> group_by(species) |> summarize(characters = n()) |> arrange(desc(characters))

starwars |>
  group_by(species) |>
  summarize(characters = n()) |>
  arrange(desc(characters))

Hint

J-327D wonders just how many hints you need, but suggests you check out arrange().
