mapboxgl_view: Quick visualization of geometries with Mapbox GL

Description

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

Usage

mapboxgl_view(
  data,
  color = "navy",
  column = NULL,
  n = NULL,
  palette = viridisLite::viridis,
  style = mapbox_style("light"),
  ...
)

Value

A Mapbox GL map object

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 Mapbox style to use. Defaults to mapbox_style("light").

...

Additional arguments passed to mapboxgl()

Examples

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

# Basic view
mapboxgl_view(nc)

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

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

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