r - 闪亮模块的两个问题

问题描述

这是一个最小的例子。我正在尝试模块化现有应用程序以分离不同的分析问题。每个问题都有一个用于输入的侧边栏面板和一个用于输出的主面板。我在为输入设置侧边栏面板时遇到两个问题。我将有两个按钮在第一个被选中后交换。此操作位于模块服务器代码中，需要读取所选分析（导航栏中的选项卡标签），然后对读取的值进行操作。我收到此问题的错误：警告：== 中的错误：比较 (1) 仅适用于原子和列表类型 44：[/appsdata/home/wk211a/Projects/vrat4/minexample.R#61] 1：runApp

第二个问题是我无法在第一个选项卡中显示简单的 renderText 消息。

这是代码：

##### Test Example

##### Setup VRAT App

ContCurrentSideBarPanelUI <- function(id){
  
  ns <- NS(id)
  
  tagList(
    
    tabsetPanel(
      id = "sbpcontin",
      tabPanel(
        "Setup",
        value = "setup_Cont_Curr",
        textOutput(ns("result"))
      ),
      tabPanel(
        "Verification",
        value = "verify_Cont_Curr"
      ),
      tabPanel(
        "Process",
        value = "process_Cont_Curr"
      ),
      tabPanel(
        "Design",
        value = "req_Cont_Curr"
      ),
      tabPanel(
        "Risk Analysis",
        value = "risk_Cont_Curr",
      ),
      tabPanel(
        "Guardbanding",
        value = "gb_Cont_Curr"
      ),
      tabPanel(
        "Sampling",
        value = "sample_Cont_Curr"
      ),
      tabPanel(
        "Decon",
        value = "decon_Cont_Curr"
      )
    )
  )
}

ContCurrentSideBarPanelServer <- function(id,appTabs,Maincount){
  moduleServer(
    id,
    function(input,output,session){
      observe({
        output$result <- renderText({
          paste0("Here I am ", 63)
        })
     })
      
      observe({
        if (appTabs == "cont_Data" ) {
          showElement(id = "goButton")
          hideElement(id = "goButton3")
        }
      })
      x <- 93
      return(x)
    }
