# R/BirdChicken.R In moviedo5/fda.tsc: Functional Data Sets for Time Series Classification

#' @title Bir/Chicken shape classification
#'
#' @description   It is used for testing contour/image and skeleton-based descriptors. Classes of images vary broadly, and include classes that are similar in shape to one another.
#'
#' @details
#' There are 20 instances of each class, and 60 classes in total. We have extracted the outlines of these images and mapped them into 1-D series of distances to the centre. Bird/Chicken is the problem of distinguishing between an outline of a bird and a chicken
#' @format
#' \describe{
#' The variables are as follows:
#' \itemize{
#' \item{\code{df}:}{ \code{data.frame} with the following variables:}
#' \itemize{
#' \item{\code{class}:}{ Corresponding class level of BirdChicken'' curves with 2 classes:level 1, n=20 and level 2, n=20.}
#' \item{\code{sample}:}{Factor variable. In TSC, the first 20 values (\code{sample=train}) are used for training sample and the rest of 20 (\code{sample=test}) for testing.}
#' }
#' \item{\code{x}:}{ \code{fdata} class object with with n=40 curves (per row) observed in 512 discretization points (per column).}
