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')
  })
})

Answer 1

您要找的是HTML anchor tag.例如,您可以使用以下方法为distPlot2创建锚点:

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

您可以替换要跳转到#的id任何HTML元素之后的内容.
