#'@title   Definition of a method for the inherited class stanfitExtended from stanfit
#'@description This is a function for a method for a generic function \code{print()} for class "\code{\link{stanfitExtended}}"
#'@param x This is an \R object of an S4 class named \code{\link{stanfitExtended}}  inherited  class from the stanfit in the rstan package.
#'@export print_stanfitExtended
#'
#'@details
#'
#' Print of stanfit has many parameters, but one of them, the AUC is the most important parameter. Thus in particular, we explain how to interprete the print out messages for AUCs.
#'
#'
#'
#'
#'    --------   Print of \code{stanfit} object  -----------------------------------------------
#'
#'
#'   * The  AUC denoted by \code{AA[modalityID , readerID]} are shown by the function \code{print()} with a stanfit object.
#'
#'   * The column of 2.5\% and 97.5\% means the lower and upper bounds of the 95% Credible Interval of AUCs.
#'
#'   * For example, \code{AA[2,3]} means the AUC of the 2 nd modality and the 3 rd reader.

#'# How to use a new method for generic function "print".

#'#=============================The First Example======================================
#'
#'
#'#(1)First, we prepare the example data from this package.
#'
#'
#'
#'                       dat  <- BayesianFROC::dataList.Chakra.1
#'
#'
#'
#'# The R object named dat is a list which contains the hits and false alarms representing
#'# an FROC dataset. To confirm it, the function viewdata() can be used;
#'
#'
#'
#'                               viewdata(dat)
#'
#'
#'
#'
#'#(2)Second, we run fit_Bayesian_FROC() in which the rstan::sampling() is implemented.
#'#Fit to data named "dat"   the author's Bayesian model by
#'
#'
#'
#'                          fit <-  fit_Bayesian_FROC(dat)
#'
#'
#'
#'
#' #(3)Thirdly, we obtain the R object fit of  S4 class
#' # named stanfitExtended that is an inherited class from the  S4 class stanfit
#' # defined in the package rstan.
#' # For the S4 class stanfitExtended defined in this package, we can use
#' # the generic function print for this new S4 class.
#'
#'
#'
#'                                print(fit)
#'
#'
#'
#'# To use the generic functin print() as a  object of class "stanfit",
#'#  we coerce class of fit into stanfit from stanfitExtended as follows;
#'
#'
#'
#'
#'                             fitt <- methods::as(fit,"stanfit")
#'
#'
#'
#'
#'# THe R object "fitt" is a fitted model object of class stanfit,
#'# thus we can also apply the generic function print() as follows:
#'
#'
#'
#'                                print(fitt)
