In the ggplot2 grammar, there is a there are geoms to add horizontal and vertical lines (geom_hline() and geom_vline()).
I see that the current version of the package includes vline and hline as parameters of scale_color_ipea() and scale_fill_ipea(). Imho, this doesn't make sense. The scale_*_ipea() should only relate to color palettes and legends. The vertical and horizontal lines we add to plots are not related to those.
