#' Equilibrium-recruitment plots
#'
#' The function \code{EqRec.plots} generates plots of quantities at equilibrium
#' as a function of fishing mortality rate \emph{F}.
#' Its operation is similar to that of function \code{PerRec.plots.}
#' It exists to allow the analyst's model to examine, in two potentially
#' different resolutions, quantities that vary with \emph{F}.
#'
#' @param x an R list with output from the assessment models.
#' @param DataName string used in plot titles. Defaults to argument \code{x}.
#' @param draft modifies plots for use in a report. When \code{FALSE} main titles
#' are omitted.
#' @param graphics.type a vector of graphics file types to which graphics are saved.
#' When \code{NULL}, no plots are saved.
#' @param use.color plots are made in grayscale when \code{FALSE}
#' @param units.L A character string (e.g. \code{"pounds"} for labeling the plot
#' of equilibrium landings.
#' @param units.SSB A character string for labeling the plot of equilibrium
#' spawning biomass.
#' @param units.B A character string used in labeling the plot of equilibrium biomass.
#' @param units.D A character string used in labeling the plot of equilibrium discards.
#' @param units.Y A character string used in labeling the plot of equilibrium yield.
#' @param units.R A character string used in labeling the plot of equilibrium recruitment.
#' @param user.xmax A user specified maximum value for the x-axis of the plots (default NULL goes to max of range)
#' @param user.Eq A list whose elements are names of additional columns of
#' \code{x$eq.series} to be plotted against \emph{F}.
#' @param legend.pos A text string compatible with the \code{legend} function of \code{R}.
#' Defines the position of the legend (ex. "bottomright", "bottom", etc.)
#' @param F.references A list of character-string vectors to specify reference
#' points to appear on \emph{F} plots.
