Making choices choice operators penguins (solution)

NoteExercise

If the file penguins.csv is not in your working directory then download it.

Load penguins.csv using read_csv(). Extract the species, island, and body_mass_g columns into vectors named species, island, and body_mass.

Use these vectors to print whether or not the following statements are TRUE or FALSE.

  1. The body mass of the first penguin is greater than 3500 g.
  2. "Emperor" is in species.
  3. The species of the first penguin is "Adelie" or its body mass is greater than 4000 g.
  4. The body mass of the second penguin is between 3700 and 3900 g.
  5. Each body mass is NA.
  6. For each observation either the island is "Torgersen" or the species is "Gentoo".
