我希望有不同的CheckboxGroupInput列選擇器基於我選擇的選項卡，但是當我打開兩個列選擇器UI的輸出條件時可見，數據加載但不顯示，列選擇器也不顯示。當我的主面板沒有兩個選項卡時，我可以使其工作。我已經在這裏工作了2天，我只是不知道這個工作的語法。我會非常感謝一些幫助，因爲我是Shiny的初學者。R閃亮無法獲得條件checkboxGroupInput基於活動選項卡

喜@Arun。你可以請提供'源（「helper.R」）' – jdharrison

嗨jd，道歉，這是幫手.R – Arun

我不知道java腳本，是否沒有其他方式來綁定一個GroupCheckBox與所選標籤？如何引用選定的選項卡？我已經搜索，但我找不到與此主題相關的任何內容。 – Arun

你有一個命名錯誤：

conditionalPanel(
     condition = "input.RSQRM == 'Asset Data'", 
     uiOutput("selectAssetCols")), 

    conditionalPanel(
     condition = "input.RSQRM == 'Stock Betas'", 
     uiOutput("selectBetaCols"))

的checkGroups對我的標籤工作條件，當我更改爲正確的選項卡名稱。因此，爲了說明您需要引用標籤名稱而不是標籤ID。

當閃亮的應用程序正在運行，你可以打開Firebug，如果你在Firefox和控制檯類型的運行

>>> Shiny.shinyapp.$inputValues.RSQRM 
"Stock Betas"

你可以看到輸入的值是「股票貝塔係數」
