#' bears: Bear's Weight and Other Measurements
#'
#' This data set contains data from a subset of the original data set `bears`
#' supplied by Gary Alt. These data were collected in the interest of estimating
#' the weight of a bear based on other measurements of the bear.
#'
#' @format A data frame with 24 observations (rows) and 12 variables (columns).
