nutrient_maps | R Documentation |
Creates maps showing basin output total or by source loads
nutrient_maps(green_file, sh_file, basin_name, plot.type, legend_position = 1)
green_file |
data frame of GREEN model results from green_shares() function. Nutrient Load by source apportionment of nutrient for each year and catchments. |
sh_file |
sf object. The spatial information of the basin. |
basin_name |
character. The title of the map. |
plot.type |
character. Alternatives of the map: “gr1”: output load (kt/y) by source; “gr2”: Total Load, log10 (kt/y); “gr3”: Total Load by km2 (kt/year/km2). |
legend_position |
numeric. Legend position: 1 (default): "right", "bottom"; 2: "left", "up"; 3: "right", "bottom"; 4: "right", "up". |
No return value, called for the side effect of drawing a plot
