闪亮的外部传单地图

Question

我正在设置一个闪亮的应用程序，并希望包含此地图： https://openweathermap.org/weathermap?basemap=map&cities=true&layer=temperature&lat=47&lon=1&zoom=6

幸运的是，传单使您可以铺彩虹。要检查哪些可用于OpenWeatherMap，请尝试

library(leaflet)
> names(providers)[grepl("OpenWeatherMap", names(providers))]
 [1] "OpenWeatherMap"                      "OpenWeatherMap.Clouds"               "OpenWeatherMap.CloudsClassic"       
 [4] "OpenWeatherMap.Precipitation"        "OpenWeatherMap.PrecipitationClassic" "OpenWeatherMap.Rain"                
 [7] "OpenWeatherMap.RainClassic"          "OpenWeatherMap.Pressure"             "OpenWeatherMap.PressureContour"     
[10] "OpenWeatherMap.Wind"                 "OpenWeatherMap.Temperature"          "OpenWeatherMap.Snow" 

因此，您可以调出温度图。请注意，您需要在服务网站上申请API密钥（来自here）。

leaflet() %>%
  addTiles() %>%
  addProviderTiles(providers$OpenWeatherMap.Temperature,
                   options = providerTileOptions(apiKey="<your_api_key_here>")) %>%
  setView(14.4220129, 46.0846989, zoom = 6)

不过，还不确定如何整合城市层。
