title: in R, ggplot geom_point() with colors based on specific, discrete values - part 2
body: <p>My question is similar to <a href="https://stackoverflow.com/questions/29966582/ggplot-geom-point-with-colors-based-on-specific-discrete-values">this one</a>, except that my data are different. In my case, I was not able to use the solution given. I would expect points to show up on my map coloured according to the cut() values. Could someone point me in the right direction?</p>
