draw.Rd
Draw on a plot (map) to get a SpatVector or SpatExtent object for later use. After calling the function, start clicking on the map. When you are done, press ESC
. You can also preset the maximum number of clicks.
This does to work well on the default RStudio plotting device. To work around that, you can first run dev.new(noRStudioGD = TRUE)
which will create a separate window for plotting, then use plot()
followed by click()
and click on the map .
