Palmer Penguins
The data this week comes from Dr. Kristen Gorman by way of the palmerpenguins R package by Dr. Kristen Gorman, Dr. Allison Horst, and Dr. Alison Hill.
Their palmerpenguins packagedown site and corresponding GitHub Repo has all the details, which I will duplicate some of below.
You can install their package for reproducible use via install.packages("palmerpenguins").
The goal of
palmerpenguinsis to provide a great dataset for data exploration & visualization, as an alternative to iris.We gratefully acknowledge Palmer Station LTER and the US LTER Network. Special thanks to Marty Downs (Director, LTER Network Office) for help regarding the data license & use.
They’ve bundled both the raw data and the cleaned data together, which I have also included here.
The main measurements are body mass, culmen (bill) length, bill depth, and flipper length.
