Arguments

data	the dataset to plot. default: us_fertilizer_county.
Year	the temporal coverage of the data to visualize. See link for available period.
Nutrient	the nutrient type of fertilizer from usfertilizer. Has to be N, P or both (NULL).
Farm_Type	the spatial source of fertilizer, should be farm, nonfarm or both.
Input_Type	the input source of fertilizer, should be manure, fertilizer.
State	the states that will show in the plot,default: all states.
County	the counties that will show in the plot, default: all counties.
FIPSs	the FIPS code for counties in USA.
fun	the function to process data, not done yet.
annual_change	to check if the data represent the annual change, default: FALSE.
level	the spatial resolution of map, should be county or state, default county.
facet	the facet to draw subplots.
trans	the transformation parameter for scale_fill_viridis.
fill_var_type	the type of data to visualize, default: Null.
viridis_palette	the palette type for viridis, options: “Viridis”,“magma”, “plasma”, "cividis", and “inferno.”
viridis_direction	Sets the order of colors in the scale. If 1, the default, colors are ordered from darkest to lightest. If -1, the order of colors is reversed.
viridis_end	The (corrected) hue in [0,1] at which the viridis colormap ends.
projection	the projection name for spatial projection.
parameters	parameters for map projection.
orientation	orientation for map projection.
xlim	x axis limits for map project.
ylim	y axis limits for map project.
add_north	logic. If TRUE, the ggplot object will include a states_shape df to draw north symbols and scale bars.
na.rm	How to deal with NA values. Default: TRUE.
coord_fix_ratio	the ratio for fixed coordinate system, default: 1.3.
map_theme	the map theme for dataset. Default: theme_map_fertilizer()

Value
