Register a geojson map.

e_map_register(e, name, json)

e_map_register_p(
  name,
  json,
  async = FALSE,
  session = shiny::getDefaultReactiveDomain()
)

e_map_register_ui(name, json, async = FALSE)

Arguments

e

An echarts4r object as returned by e_charts.

name

Name of map, to use in e_map.

json

Geojson.

async

Whether to read the file asynchronously.

session

A valid Shiny session.

Details

e_map_register_p is not truly a proxy as it does not require a chart to function. While the function e_map_register_ui is meant to register the map globally in the Shiny UI, not that then json must be accessible from the UI (generally www folder).

Examples

if (FALSE) { json <- jsonlite::read_json("http://www.echartsjs.com/gallery/data/asset/geo/USA.json") USArrests %>% dplyr::mutate(states = row.names(.)) %>% e_charts(states) %>% e_map_register("USA", json) %>% e_map(Murder, map = "USA") %>% e_visual_map(Murder) }
