闪亮：如何将sidebarPanel嵌入tabPanel中？

Question

我试图在一个单独的选项卡中有一个selecInput面板，但我不确定该怎么做。在函数tabPanel（）内，我尝试在函数plotOutput（）之后立即包含sidebarPanel（），但是sidebarPanel不再位于侧面，而是位于左侧，并且与直方图重叠。是否有一种方法可以将侧面板正确地嵌入到特定的选项卡中，或者将侧面板显示在图形的右侧？谢谢，下面是我使用的代码：

mainPanel(
    tabsetPanel(
      tabPanel("Histogram",plotOutput("histogram")),
      tabPanel("Scatter",plotOutput("scatter"),
               sidebarPanel(
  selectInput("xaxis", label = "x axis",
              choices = detectors, selected = detectors[1],width='200px',selectize=FALSE),
  selectInput("yaxis", label = "y axis",
              choices = detectors, selected = detectors[2],width='200px',selectize=FALSE),
  selectInput("population1", label = "Population 1",
              choices = files, selected = files[1],width='200px',selectize=FALSE),
  selectInput("population2", label = "Population 2",
              choices = files, selected = files[1],width='200px',selectize=FALSE),
  selectInput("population3", label = "Population 3",
              choices = files, selected = files[1],width='200px',selectize=FALSE)
  )
),
      tabPanel("Table", DT::dataTableOutput("table"))
    )
)

您的概念正确，但是代码放置错误。通过下面的代码是不言自明的。

library(shiny)
ui <- fluidPage(


   titlePanel("Old Faithful Geyser Data"),

   tabsetPanel(               
           tabPanel("Tab 1", h1("First tab") ),
           tabPanel("Tab2",
             sidebarLayout(
               sidebarPanel(width = 3, sliderInput("bins",
                                                   "Number of bins:",
                                                   min = 1,
                                                   max = 50,
                                                   value = 30)
               ),

               mainPanel(
                 plotOutput("distPlot")
             )
           )
       )
   )
)
server <- function(input, output) {

   output$distPlot <- renderPlot({
      x    <- faithful[, 2] 
      bins <- seq(min(x), max(x), length.out = input$bins + 1)

      hist(x, breaks = bins, col = 'darkgray', border = 'white')
   })
}
shinyApp(ui = ui, server = server)*
