I had a question from workshop participants about the example map shown with two of the three types of vectors, asking why the point in the legend is plotted on top of a line.
Might it be preferable to remove the option show.legend = "line" ? I realize that the polygons are then shown in the legend as a square and perhaps it was intentional to have it shown as a line, so the point legend could also just be something to discuss and refer participants to later when they learn mapping with ggplot.
