|
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). |
County |
the counties that will show in the plot, default: all counties. |
State |
the states that will show in the plot,default: all states. |
Farm_Type |
the spatial source of fertilizer, should be farm, nonfarm or both. |
Input_Type |
the input source of fertilizer, should be manure, fertilizer. |
lat_max |
the maximum latitude of area of interest. |
lat_min |
the minmum latitude of area of interest. |
long_max |
the maximum longitude of area of interest. |
long_min |
the minimum longitude of area of interest. |
FIPSs |
FIPS numbers of interest, defalut: all the counties. |
overlap_state_county |
Logic. If true, the function will overlaping the input of states and counties. If false, the function will return results either in the states or in the counties. |
combine_state_county |
Logic. If true, the county will be changed into county, state, e.g. Wake, NC; If false, no changes. |
fun |
the function to process data, not done yet. |
annual_change |
to check if the data represent the annual change, default: FALSE. |
facet |
the facet to draw subplots. |
level |
the spatial resolution of map, should be county or state, default county. |
na.rm |
How to deal with NA values. Default: TRUE. |
... |
extra parameters for |
A tibble with tidy data.
