#' Diagnostic plots for the replicate estimated parameter values in an evmBoot object
#' @param data An object of class 'evmBoot'.
#' @param denscol Colour for the densities. Defaults to 'light blue'.
#' @param histcol Colour for the histograms. Defaults to 'dark blue'.
#' @param linecol Colour for the point estimate lines. Decaults to 'orange'.
#' @param plot.it Whether or not to actually print the plots. Defaults
#'     to \code{plot.it=TRUE}.  If \code{plot.it=FALSE}, you might
#'     want to control the layout. Do this with
#'     \code{do.call("grid.arrange", c(plots, ncol=2))}, for example,
#'     where \code{plots} is the objected returned by
#'     \code{ggplot.evmBoot}.
#' @param mapping,environment ignored
#' @param ... Additional arguments to \code{ggplot}, currently unused.
