Rでplotly_clickとを使用して複数のインフォボックスの更新plotly

Question

スクリプトを実行してください場合は、それはあなたのplotly Rとで基本的なサンキーチャートやほかのデータテーブルを与える

。また、上には3つのinfoBoxがあります。私はプロットのサンキーラインをクリックすると、私はplotly_clickを使用してデータテーブル内の値を参照してください。私は2番目のインフォボックスで3により、機能私はどのサンキー行をクリックしたときに、それがデータテーブルに「POINTNUMBER」列の値をピックアップして、2で乗算し、最初のインフォボックスに入れて欲しい、とのように第三インフォボックスに4を掛けスナップ付き。ありがとう、助けてください。 event_data()を考慮

はデータフレーム、次のコードアクセス特定の値pointNumberを出力し、動的UIをレンダリングします。

コード：

    } else 
     d

    output$box1 <- renderUI({ 
    tagList(

    infoBox("Multiply by 2", event_data("plotly_click")$pointNumber * 2, icon = icon("credit-card")),
