+#' Coordinate systems interact with many parts of the plotting system. You can
+#' expect the following for `coord_flip()`:
+#'
+#' * It does *not* change the facet order in `facet_grid()` or `facet_wrap()`.
+#' * The `scale_x_*()` functions apply to the vertical direction,
+#'   whereas `scale_y_*()` functions apply to the horizontal direction. The
+#'   same holds for the `xlim` and `ylim` arguments of `coord_flip()` and the
+#'   `xlim()` and `ylim()` functions.
+#' * The x-axis theme settings, such as `axis.line.x` apply to the horizontal
+#'   direction. The y-axis theme settings, such as `axis.text.y` apply to the
+#'   vertical direction.
