r - Shinydashboard 登陆页面

Question

当使用带有 shinyDashboard 的 runApp() 时，应用程序默认加载第一个选项卡。有什么方法可以将第一页更改为“欢迎”之类的内容，而不是直接加载第一个选项卡？

Answer 1

You can add an updateTabItems command in your server.R

If you want it to fire when the application starts you'll want to put it inside an observe

observe({
  updateTabItems(session, "menuTabId", 'tabIdToChangeTo')
})

If you want this functionality to repeat depending on some value, you'll want to add a reactive input or reactive value inside the observe scope to trigger the observe once that value changes.
