Default is NULL (uses length of categories).} \item{background}{Character. Background/default color for unassigned categories. Default is "#f8f8f8".} } \value{ A list of color mappings suitable for pmColors() or addProtomaps(colors=). } \description{ Maps colors from a palette to land use categories, enabling use of viridis, RColorBrewer, and other R color palettes with Protomaps. } \examples{ \dontrun{ library(leaflet) library(protomapr) # Using viridis palette for land use if (requireNamespace("viridisLite", quietly = TRUE)) { colors <- pmPalette(viridisLite::viridis(6)) leaflet() \%>\% setView(lng = -122.4, lat = 37.8, zoom = 12) \%>\% addProtomaps(url = protomaps_url(), colors = colors) } # Using RColorBrewer if (requireNamespace("RColorBrewer", quietly = TRUE)) { colors <- pmPalette(RColorBrewer::brewer.pal(6, "Set2")) leaflet() \%>\% setView(lng = -122.4, lat = 37.8, zoom = 12) \%>\% addProtomaps(url = protomaps_url(), colors = colors) } # Custom category mapping colors <- pmPalette( c("#264653", "#2a9d8f", "#e9c46a", "#f4a261", "#e76f51"), categories = c("water", "park", "sand", "buildings", "highway") ) } } \seealso{ \code{\link{pmPaletteStyle}}, \code{\link{pmColors}} }
