make_polygons | R Documentation |
This function coerces all rectangles from a 'ggplot' object to 'SpatialPolygonDataFrame'.
make_polygons(
ggplot_object,
north = 3454206.89,
east = 5939183.21,
projection_input = "+init=epsg:31467",
projection_output = "+init=epsg:4326"
)
ggplot_object |
saved ggplot object, containing the coordinates of the rectangles of a 'ggplot' object of the first two layers |
north |
float added to the rows to have a northing ordinate |
east |
float added to the rows to have a easting ordinate |
projection_input |
string defines in which EPSG projection the ggplot object should be converted to a raster object? a projection with a metric unit is highly recommended |
projection_output |
string defines in which EPSG projection the SpatialPolygonDataFrame should be exported. |
