-#' Plot a fitted nonlinear mixed model obtained via an mmkin row object

-#' @param i A numeric index to select datasets for which to plot the nlme fit,
-#'   in case plots get too large
-#' @inheritParams plot.mkinfit
-#' @param standardized Should the residuals be standardized? Only takes effect if
-#'   `resplot = "time"`.
-#' @param rel.height.legend The relative height of the legend shown on top
-#' @param rel.height.bottom The relative height of the bottom plot row
-#' @param ymax Vector of maximum y axis values
-#' @param ncol.legend Number of columns to use in the legend
-#' @param nrow.legend Number of rows to use in the legend
-#' @param resplot Should the residuals plotted against time or against
-#'   predicted values?
-#' @param col_ds Colors used for plotting the observed data and the
-#'   corresponding model prediction lines for the different datasets.
-#' @param pch_ds Symbols to be used for plotting the data.
-#' @param lty_ds Line types to be used for the model predictions.
-#' @importFrom stats coefficients
-#' @return The function is called for its side effect.
