I have to add a point on a existing
spplot in R. I need it only for a visual purpose. I have the coordinates of the point, but I don't know how to change the code in order to add the point.
This is the code of the
The coordinates of the point are X=720731,8704 and Y=4861300,795 in the reference system WGS 84 / UTM zone 32N EPSG:32632, the same system of the plot.
Anyone can help me?
