buffer = NULL,

style = "pretty",
palette = pal_reach("red_5"),
as_count = TRUE,
color_na = cols_reach("white"),

)
}
\arguments{
\item{poly}{Multipolygon shape defined by sf package.}
\item{col}{Numeric attribute to map.}
\item{buffer}{A buffer, either one value or a vector of 4 values (left, bottom, right, top).}
\item{n}{The desire number of classes.}
\item{style}{Method to process the color scale for continuous numerical variables. See `classInt::classIntervals()` for details.}
\item{palette}{Vector of fill colors as hexadecimal values. For REACH color palettes, it is possible to use `pal_reach()`. For now,'palette' must be changed manually, accordingly to the number of drawn classes.}
\item{as_count}{Boolean. When col is a numeric variable, should it be processed as a count variable? For instance, 0, 1-10, 11-20.}
\item{color_na}{Fill color for missing data.}
\item{text_na}{Legend text for missing data.}
\item{legend_title}{Legend title.}
\item{legend_text_separator}{Text separator for classes. E.g. " to " will give 0, 1 to 10, 11 to 20.}
\item{border_alpha}{Transparency of the border.}
\item{border_col}{Color of the border.}
\item{lwd}{Linewidth of the border.}
\item{...}{Other arguments to pass to `tmap::tm_polygons()`.}
}
\value{
A tmap layer.
