javascript - 在闪亮的应用程序中将价值从谷歌地图转移到 rchart

Question

我有一个闪亮的应用程序，我在其中绘制了一个带有plotGoogleMaps和 的地图rChart，其值与地图中的某些标记相关，通过rPlot.

应用程序用户可以单击地图中的标记以显示工具提示。

我希望当他点击标记时，图表中的相关值会突出显示。

有人知道如何执行此任务吗？

谢谢你。

R代码可以是这样的：

suppressPackageStartupMessages(library(googleVis))

## Hurricane Andrew (1992) storm track with Google Maps
AndrewMap <- gvisMap(Andrew, "LatLong", "Tip", options = list(showTip = TRUE, 
showLine = TRUE, enableScrollWheel = TRUE, mapType = "hybrid", useMapTypeControl = TRUE))

print(AndrewMap, "chart")

该示例取自此处。您可以在此处下载该软件包。在这个例子中，使用了库googleVis，但我认为答案可能是相似的。

    return (AndrewMap)

  output$info <- renderPrint ({
    cat ('Hurricane\n')
    cat ('Pressure=937\n')

  })

}
