#' Size measurements for adult foraging penguins near Palmer Station, Antarctica
#'
#' These data are copied and lightly modified from the `penguins` data in
#'  the [palmerpenguins](https://allisonhorst.github.io/palmerpenguins/) R
#'  package. The only modification is removal of rows
#'  with missing data. The data include measurements for penguin species,
#'  island in Palmer Archipelago, size (flipper length, body mass, bill
#'  dimensions), and sex.
#'
#' @format A tibble with 333 rows and 8 variables:
#' \describe{
#'   \item{species}{a factor denoting penguin species (Adélie, Chinstrap and Gentoo)}
#'   \item{island}{a factor denoting island in Palmer Archipelago, Antarctica (Biscoe, Dream or Torgersen)}
#'   \item{bill_length_mm}{a number denoting bill length (millimeters)}
#'   \item{bill_depth_mm}{a number denoting bill depth (millimeters)}
#'   \item{flipper_length_mm}{an integer denoting flipper length (millimeters)}
#'   \item{body_mass_g}{an integer denoting body mass (grams)}
#'   \item{sex}{a factor denoting penguin sex (female, male)}
#'   \item{year}{an integer denoting the study year (2007, 2008, or 2009)}
#' }
