R DATASET

The goal of palmerpenguins is to provide a great dataset for data exploration & visualization, as an alternative to iris. The latest CRAN release was published on 2020-07-25.

DATA COLLECTION

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.
