Size measurements for adult foraging penguins near Palmer Station,
Antarctica

Description:

     Includes measurements for penguin species, island in Palmer
     Archipelago, size (flipper length, body mass, bill dimensions),
     and sex. This is a subset of ‘penguins_raw’.

Usage:

     penguins <- read.csv("https://raw.githubusercontent.com/roualdes/data/master/penguins.csv")

Format:

     A tibble with 344 rows and 8 variables:

     species a factor denoting penguin species (Adélie, Chinstrap and
          Gentoo)

     island a factor denoting island in Palmer Archipelago, Antarctica
          (Biscoe, Dream or Torgersen)

     bill_length_mm a number denoting bill length (millimeters)

     bill_depth_mm a number denoting bill depth (millimeters)

     flipper_length_mm an integer denoting flipper length (millimeters)

     body_mass_g an integer denoting body mass (grams)

     sex a factor denoting penguin sex (female, male)

     year an integer denoting the study year (2007, 2008, or 2009)
