如何在selectInput上选择不同的值

我想将我的csv数据引入这个应用程序，这个应用程序附在这个问题之后：我的目标是确保无论用户选择什么，这两个select输入都加载了不同的值！我的代码的问题是，第一个selectInput被阻止为相同的初始值，而它必须更改并防止第二个每次都有其值

ui <- fluidPage(
    fileInput('file1', 'Upload your  CSV File'),
    htmlOutput("variables"),
    htmlOutput("facteurs"),
    uiOutput("tb"))
server <- function(input, output, session) {
  myData1 <- reactive({
    inFile <- input$file1
    if (is.null(inFile)) return(NULL)
    data <- read.csv(inFile$datapath, header = TRUE,row.names=1)
    data
  })
  output$variables <- renderUI({
    df_init <- myData1() 
    x=sapply(df_init,class)
    x=(x=="numeric")
    df=df_init[,x]
    if (identical(df, '') || identical(df,data.frame())) return(NULL)
    selectInput(inputId = "V1", label = "Variables to use: Y", choices=names(df), selected=names(df[1]))
  })
  output$facteurs <- renderUI({
    df_init <- myData1() 
     x=sapply(df_init,class)
    x=(x=="factor")
    df=df_init[,x]
    if (identical(df, '') || identical(df,data.frame())) return(NULL)
       verticalLayout(
        selectInput(inputId = "F11", label = "Factors to use: X1", choices=names(df)),
        selectInput(inputId = "F12", label = "Factors to use: X2", choices=names(df)[names(df)!=input$F11]))
   })}
shinyApp(ui = ui, server = server)

欢迎来到Stackoverflow。我是《闪亮的代码》方面的专家，目前来看，这个问题无法回答。我建议暂时搁置这一问题，直到提供进一步的细节。请编辑您的问题，以包含您的

应用程序的所有代码。此外，您需要准确描述您想要做什么，并提供/描述一些示例数据。如需指导，请查看页面和。欢迎！一个可复制的例子确实会有帮助。在服务器端，您可以使用smthg，比如
output$UIF12。我已经用更好的方式更新了这个问题！
