Penguins.data: Size Measurements of Penguins

Description

This data is from a study of three penguin species from three islands in the Palmer Archipelago, Antarctica. Four measurements were collected for 344 male and female penguins in the years 2007 - 2009.

Usage

Penguins.data

Format

A data frame with 344 observations (rows) and 8 variables (columns).

	Column name	Data type	Description	Values
[,1]	species	factor	3 different penguin species	(Adelie, Chinstrap, Gentoo)
[,2]	island	factor	3 different islands	(Biscoe, Dream, Torgersen)
[,3]	bill_length	numeric	Culmen length in mm	(32.10 - 59.60)
[,4]	bill_depth	numeric	Bill depth in mm	(13.10 - 21.50)
[,5]	flipper_length	integer	Flipper length in mm	(172.0 - 231.0)
[,6]	body_mass	integer	The penguin's body mass in gram	(2700 - 6300)
[,7]	sex	factor	The gender of the penguin	(female, male)
[,8]	year	integer	The year of the study	(2007 - 2009)

The bill_length is a measurement of the culmen length: the penguin's upper ridge of the bill (beak).

Details

The data is from the palmerpenguins data package which also contains a data set penguins_raw with additional information from the study.
