#' Observations (DV) plotted against individual predictions (IPRED) for Xpose 4
#'
#' This is a plot of observations (DV) vs individual predictions (IPRED), a
#' specific function in Xpose 4. It is a wrapper encapsulating arguments to the
#' \code{xpose.plot.default} function. Most of the options take their default
#' values from xpose.data object but may be overridden by supplying them as
#' arguments.
#'
#' A wide array of extra options controlling \code{\link[lattice]{xyplot}} are
#' available. See \code{\link{xpose.plot.default}} and
#' \code{\link{xpose.panel.default}} for details.
#'
#' @param object An xpose.data object.
#' @param abline Vector of arguments to the \code{\link[lattice]{panel.abline}}
#' function. No abline is drawn if \code{NULL}.
#' @param smooth Logical value indicating whether an x-y smooth should be
#' superimposed. The default is TRUE.
#' @param \dots Other arguments passed to \code{link{xpose.plot.default}}.
#' @return Returns an xyplot of DV vs IPRED.
