#' Body Fat of Little Brown Bat
#'
#' A dataset containing the percent body fat of little brown bats sampled in
#' Aeolus Cave, located in East Dorset, Vermont, in the North Eastern United States.
#'
#' @usage data(bodyfat_Aeolus)
#' @format A data frame with 159 rows and 4 variables:
#' \describe{
#'   \item{sex}{sex of the sampled bat, \code{M} for masculine and \code{F} for
#'        feminine.}
#'   \item{percentfat}{percent body fat.}
#'   \item{year}{year the bat was sampled.}
#'   \item{days}{hibernation time, defined as days since the fall equinox.}
#' }
#' @details The complete dataset was collected by Cheng et al. (2019) in five
#'     different regions of the United States. \code{bodyfat_Aeolus} is the subset
#'     of the data collected in Aeolus Cave, located in East Dorset, Vermont,
#'     in the North Eastern United States.
