创建指向闪亮应用程序其他部分的链接 [英] Create link to the other part of the Shiny app

问题描述

我想知道是否可以创建一个指向闪亮应用程序其他部分的链接。我的意思是，我有一个带有Itroductiion、Plot 1和Plot 2面板的页面报告。在Introduction面板内，我想添加Plot 1和Plot 2面板的引用，以便在单击链接后立即查看此绘图。有可能吗？

ui.R

library(shiny)

shinyUI(
  fluidPage(
  fluidPage(
    titlePanel("Introduction"),
    column(12,
    p("Lorem ipsum dolor sit amet, consectetur adipisicing elit. Proin
      nibh augue, suscipit a, scelerisque sed, lacinia in, mi. Cras vel
      lorem. Etiam pellentesque aliquet tellus. Phasellus pharetra nulla
      ac diam. Quisque semper justo at risus. Donec venenatis, turpis vel
      hendrerit interdum, dui ligula ultricies purus, sed posuere libero 
      dui id orci. Nam congue, pede vitae dapibus aliquet, elit magna 
      vulputate arcu, vel tempus metus leo non est. Etiam sit amet lectus
      quis est congue mollis. Phasellus congue lacus eget neque. Phasellus
      ornare, ante vitae consectetuer consequat, purus sapien ultricies 
      dolor, et mollis pede metus eget nisi. Praesent sodales velit quis
      augue. Cras suscipit, urna at aliquam rhoncus, urna quam viverra nisi,
      in interdum massa nibh nec erat."))
    ),
  fluidPage(

  titlePanel("Hello Shiny!"),

  sidebarLayout(
    sidebarPanel(
      sliderInput("bins",
                  "Number of bins:",
                  min = 1,
                  max = 50,
                  value = 30)
    ),

    mainPanel(
      plotOutput("distPlot")
    )
  )
),
fluidPage(

  titlePanel("Hello Shiny!"),

  sidebarLayout(
    sidebarPanel(
      sliderInput("bins",
                  "Number of bins:",
                  min = 1,
                  max = 50,
                  value = 30)
    ),

    mainPanel(
      plotOutput("distPlot2")
    )
  )
))
)

server.R

library(shiny)

shinyServer(function(input, output) {
  output$distPlot <- renderPlot({
    x    <- faithful[, 2]  # Old Faithful Geyser data
    bins <- seq(min(x), max(x), length.out = input$bins + 1)

    hist(x, breaks = bins, col = 'darkgray', border = 'white')
  })
  output$distPlot2 <- renderPlot({
    x    <- faithful[, 2]  # Old Faithful Geyser data
    bins <- seq(min(x), max(x), length.out = input$bins + 1)

    hist(x, breaks = bins, col = 'darkgray', border = 'white')
  })
})

HTML

您要查找的是推荐答案anchor tag。 例如，您可以使用以下命令创建到DistPlot2的锚点：

column(12,p(HTML("intro text <a href='#distPlot2'>Go to plot 2</a> intro text "))))

您可以将#后面的内容替换为id要跳转到的任何HTML元素。
