|---|---|
| Description: | Size measurements, clutch observations, and blood isotope ratios for adult foraging Adélie, Chinstrap, and Gentoo penguins observed on islands in the Palmer Archipelago near Palmer Station, Antarctica. Data were collected and made available by Dr. Kristen Gorman and the Palmer Station Long Term Ecological Research (LTER) Program. |

The data in each file is the same as penguins and penguins_raw,
but without the variable types.
This function is adapted from readxl::readxl_example().

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.
