Interactive choropleth map of a pkmapr sf object — pk_map

Produces an interactive leaflet map. Returns a leaflet object that can be extended with standard leaflet functions.

Usage

pk_map_interactive(x, fill = NULL, popup = NULL, ...)

Arguments

x: An sf object.
fill: Character. Column name for choropleth fill. NULL produces an outline map.
popup: Character vector. Column names to display in click popups.
...: Additional arguments passed to leaflet::addPolygons().

Value

Returns a leaflet object (class "leaflet" and "htmlwidget") representing an interactive web map.

When fill = NULL, the output shows polygon outlines only.

When a fill variable is provided, the output renders polygons with:

fillColor: Color-coded by the fill variable using the viridis palette
fillOpacity: 0.7 (semi-transparent for layer visibility)
color: White borders for polygon boundaries
popup: HTML popups showing selected attributes on click

The map includes a legend for the fill variable and uses the CartoDB.Positron tile provider as the basemap.

Examples

# \donttest{
districts <- get_districts()
pk_map_interactive(districts,
                   fill = "area_km2",
                   popup = c("district_name", "area_km2"))

# }
