Quick visualization of geometries with MapLibre GL

This function provides a quick way to visualize sf geometries using MapLibre GL JS. It automatically detects the geometry type and applies appropriate styling.

Usage

maplibre_view(
  data,
  color = "navy",
  column = NULL,
  n = NULL,
  palette = viridisLite::viridis,
  style = carto_style("positron"),
  ...
)

Arguments

data: An sf object to visualize
color: The color used to visualize points, lines, or polygons if column is NULL. Defaults to "navy".
column: The name of the column to visualize. If NULL (default), geometries are shown with default styling.
n: Number of quantile breaks for numeric columns. If specified, uses step_expr() instead of interpolate().
palette: Color palette function that takes n and returns a character vector of colors. Defaults to viridisLite::viridis.
style: The MapLibre style to use. Defaults to carto_style("positron").
...: Additional arguments passed to maplibre()

Value

A MapLibre GL map object

Examples

if (FALSE) { # \dontrun{
library(sf)
nc <- st_read(system.file("shape/nc.shp", package = "sf"))

# Basic view
maplibre_view(nc)

# View with column visualization
maplibre_view(nc, column = "AREA")

# View with quantile breaks
maplibre_view(nc, column = "AREA", n = 5)

# Custom palette examples
maplibre_view(nc, column = "AREA", palette = viridisLite::mako)
maplibre_view(nc, column = "AREA", palette = function(n) RColorBrewer::brewer.pal(n, "RdYlBu"))
maplibre_view(nc, column = "AREA", palette = colorRampPalette(c("red", "white", "blue")))
} # }
