The function takes a dataset of SLF occurrences and displays a map of the spread over time. The "zoom" option allows for a customized focus of the map
map_spread(
resolution = "10k",
zoom = "range",
xlim_coord = NULL,
ylim_coord = NULL,
rarefy = TRUE,
color_palette = "plasma",
print_message = TRUE
)Defines the resolution at which the data is displayed. `"1k"` resolution shows data aggregated at a 1km2 grid, while `"10k"` shows tiles aggregated at a 10km2 grid
Defines the limits of the map to be plotted. `"range"` limits the map to the established range for SLF; `"full"` displays the whole United States. `"custom"` the user to specify the range over which the map should be displayed (see `xlim_coord, ylim_coord` below).
Ordered numerical vectors of length 2 determining the longitudinal (`xlim`) and latitudinal (`ylim`) boundaries of the map, to be expressed as decimal degree coordinates. Unnecessary if zoom is set to any value other than `"custom"`
Logical value (`TRUE/FALSE`). Specifies whether the data should be summarized for faster plotting. Overwritten and set to `TRUE` when zoom is full and/or the resolution is 10k.
A character string indicating the color option to use. Five options are available: "magma" (or "A"), "inferno" (or "B"), "plasma" (or "C"), "viridis" (or "D", the default option) and "cividis" (or "E").
Logical value. Can be set to `FALSE` to shut down the warning on run time.
