I wanted to make a simple plot of four
sf-objects which don't contain much more than the
sfc-column and some postal-code information.
sf-objects have the names
level 1-4 and
plz. What I would like to have is a simple legend next to my map just showing the names of the objects
(level 1-4) and plz and their matching colours.
It seems like a task which would be so easy in any desktop-gis, but I'd really like to do it in
R. My code so far looks like this and produced the follwing figure.
ggplot() + geom_sf(data = level3, fill = fil.a) + geom_sf(data = level2, fill = fil.b) + geom_sf(data = level1, fill = fil.c) + geom_sf(data = plz, fill = "red") + coord_sf()
