#' Absolute weighted residuals vs covariates for Xpose 4
#'
#' This creates a stack of box and whisker plot of absolute population weighted
#' residuals (|WRES| or |iWRES|) vs covariates. It is a wrapper encapsulating
#' arguments to the \code{xpose.plot.bw} function. Most of the options take
#' their default values from the xpose.data object but may be overridden by
#' supplying them as arguments.
#'
#' Each of the covariates in the Xpose data object, as specified in
#' \code{object@Prefs@Xvardef$Covariates}, is evaluated in turn, creating a
#' stack of plots.
#'
#' A wide array of extra options controlling box-and-whisker plots are
#' available. See \code{\link{xpose.plot.bw}} for details.
#'
#' @param object An xpose.data object.
#' @param xlb A string giving the label for the x-axis. \code{NULL} if none.
#' @param main The title of the plot. If \code{"Default"} then a default title
#' is plotted. Otherwise the value should be a string like \code{"my title"} or
#' \code{NULL} for no plot title.
#' @param \dots Other arguments passed to \code{\link{xpose.plot.bw}}.
#' @return Returns a stack of box-and-whisker plots of |WRES| vs covariates.
