存储数据闪亮

Question

我尝试根据操作按钮读取数据，但我无法访问其他表达式中的数据。我尝试了不同的方法，但都没有用。

S.Data <- observeEvent(input$RawGo,{

    read.maimages(files = targets$FileName, source = input$imageS, 
                  path = "Raw data/", green.only = T)
})

另一种方式：

    observeEvent(input$RawGo,{

    S.Data <- read.maimages(files = targets$FileName, source = input$imageS, 
                  path = "Raw data/", green.only = T)
})

另一种方式：

        observeEvent(input$RawGo,{

    S.Data <- reactive({read.maimages(files = targets$FileName, source = input$imageS, 
                  path = "Raw data/", green.only = T)
    })
})

没有任何效果。

完整代码

  output$RawButton <- renderUI({
if(!is.null(input$File1)){

  if(input$imageS != "Other"){
    actionButton(inputId = "RawGo", label = "Read data", icon = icon("upload"))
  } else{
    actionButton(inputId = "RawGo", label = "Read data, if import is correctly", icon = icon("upload"))
  }

}

})


S.Data <- reactive({input$RawGo;isolate({
targets = readTargets(input$File1$datapath, sep=input$sep)

  if(input$imageS != "Other" & input$datatype == "One"){
      read.maimages(files = targets$FileName, source = input$imageS, 
                  path = "Raw data/", green.only = T)
  }else if(input$imageS != "Other" & input$datatype == "Two"){
      read.maimages(files = targets$FileName, source = input$imageS, 
                  path = "Raw data/")
  }else if(input$imageS == "Other" & input$datatype == "One" & input$RawCBack == "Y"){
      read.maimages(files = targets$FileName, 
                  path = "Raw data/",
                  columns=list(G=input$RawProbe, Gb=input$RawBack),
                  green.only = T)
  }else if(input$imageS == "Other" & input$datatype == "One" & input$RawCBack == "N"){
      read.maimages(files = targets$FileName, 
                  path = "Raw data/",
                  columns=list(G=input$RawProbe),
                  green.only = T)
  }else if(input$imageS == "Other" & input$datatype == "Two" & input$RawCBack == "Y"){
      read.maimages(files = targets$FileName, 
                  path = "Raw data/",
                  columns=list(G=input$RawProbe, Gb=input$RawBack, R=input$RawProbeR,Rb=input$RawBackR))
    }else if(input$imageS == "Other" & input$datatype == "Two" & input$RawCBack == "N"){
        read.maimages(files = targets$FileName, 
                  path = "Raw data/",
                  columns=list(G=input$RawProbe, R=input$RawProbeR))
    }
  })
})

output$PrePMis<- renderUI({

D.Data <- S.Data()    

  })
})

输出$ PrePMis在另一个标签中。当我使用输出$ PrePMis

转到选项卡时，代码独立于按钮并执行
