Data notes

Where the data comes from, and what is missing.

Show the code

library(dplyr)
data(penguins)

The data are included in base R as datasets::penguins (R ≥ 4.5), so there is nothing to download. It is the Palmer Station penguin survey, the same data used in the analysis page.

Here is what is missing, by column:

Show the code

penguins |>
  summarise(across(c(bill_len, bill_dep, body_mass), \(x) sum(is.na(x)))) |>
  knitr::kable()

Table 1: Missing values per measurement column.

bill_len	bill_dep	body_mass
2	2	2

Dropping incomplete rows removes only a few observations.
