Intro Part 4

Filtering data

Our editor droid J-327D has seen that you can select specific columns (or variables) from our list of characters in the Star Wars world. But now he is curious to see more about his own kind.

J-327D asks if you can list just the droid characters in the data?

Solution

starwars |> filter(species == "Droid")

starwars |>
  filter(species == "Droid")

Hint 1

J-327D suggests you check out filter() function from the tidyverse.

Hint 2

J-327D notes there are a number of functions and operators that are useful when building a filter. He points out a tricky one: == tests if both sides of an equation are true. It is sometimes confused with =, which typically sets a variable name.
