单张闪亮的地图标记

天文学家的乐趣

我仍然是R-newb，但我正在获得一些吸引力。主要是因为我正在阅读此处的所有帖子。但是，我找不到任何信息。

我追求的是：

当用户单击传单中的标志时，将初始化我分配的ID（在该点上），然后使用该ID查询另一个Datable以构建图形。

我的问题是尝试使ID正常工作-似乎没有任何点击返回。我想知道是否与我的反应物无关？我之所以这样说，是因为我能够将其用于一个更简单的示例。
我突出了并加粗了观察语句和相应的代码。

我将向您展示一个较小的示例。

注意事项

点击的形状/地图对象将返回lat，lng和id值
该id值是您addMarkers()使用layerId参数在调用内分配的值
然后id，假设您已使用数据中的ID值作为layerId

例

在此示例中，我使用了googleway包装随附的数据集

library(shiny)
library(leaflet) 
library(googleway)

ui <- fluidRow(
  leafletOutput(outputId = "map"),
  tableOutput(outputId = "table")
)

server <- function(input, output){

  ## I'm using data from my googleway package
  df <- googleway::tram_stops

 ## define the layerId as a value from the data
  output$map <- renderLeaflet({
    leaflet() %>%
      addTiles() %>%
      addMarkers(data = df, lat = ~stop_lat, lng = ~stop_lon, layerId = ~stop_id)
  })

  ## observing a click will return the `id` you assigned in the `layerId` argument
  observeEvent(input$map_marker_click, {

    click <- input$map_marker_click

    ## filter the data and output into a table
    output$table <- renderTable({
      df[df$stop_id == click$id, ]
    })
  })

}
