![palmerpenguins](https://github.com/allisonhorst/palmerpenguins/raw/master/man/figures/logo.png) ## Description The goal of palmerpenguins is to provide a great dataset for data exploration & visualization, as an alternative to iris. Data were collected and made available by Dr. Kristen Gorman and the Palmer Station, Antarctica LTER, a member of the Long Term Ecological Research Network. Please see [https://github.com/allisonhorst/palmerpenguins](https://github.com/allisonhorst/palmerpenguins) for more information. ## Citation Anyone interested in publishing the data should contact [Dr. Kristen Gorman](https://www.uaf.edu/cfos/people/faculty/detail/kristen-gorman.php) about analysis and working together on any final products. From Gorman et al. (2014): _"Individuals interested in using these data are expected to follow the US LTER Network’s Data Access Policy, Requirements and Use Agreement: https://lternet.edu/data-access-policy/."_ This dataset has been derived from the R package palmerpenguins available from [https://allisonhorst.github.io/palmerpenguins/](https://allisonhorst.github.io/palmerpenguins/). Please cite as follows in publications: Horst AM, Hill AP, Gorman KB (2020). palmerpenguins: Palmer Archipelago (Antarctica) penguin data. R package version 0.1.0. https://allisonhorst.github.io/palmerpenguins/ A BibTeX entry for LaTeX users is: @Manual{, title = {palmerpenguins: Palmer Archipelago (Antarctica) penguin data}, author = {Allison Marie Horst and Alison Presmanes Hill and Kristen B Gorman}, year = {2020}, note = {R package version 0.1.0}, url = {https://allisonhorst.github.io/palmerpenguins/}, } ## Artwork You can download palmerpenguins art (useful for teaching with the data) from the Github repo or the R package.

In this simplified dataset, culmen length and depth are renamed as variables bill_length_mm and bill_depth_mm to be more intuitive. For this penguin data, the culmen (bill) length and depth are measured as shown below (thanks Kristen Gorman for clarifying!):
