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

您正在寻找的是 HTML anchor tag .
例如，您可以使用以下命令为 distPlot2 创建一个 anchor :

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

您可以替换 # 后面的内容由 id您想要跳转到的任何 HTML 元素。
