Type function for plotting polygons. Arguments are passed to polygon.
type_polygon(density = NULL, angle = 45)
density
|
the density of shading lines, in lines per inch. The default value of NULL means that no shading lines are drawn. A zero value of density means no shading nor filling whereas negative values and NA suppress shading (and so allow color filling).
|
angle
|
the slope of shading lines, given as an angle in degrees (counter-clockwise). |

# Use `type_polygon()` to pass extra arguments for customization
