推荐答案

这是部分答案，为您提供一些具有一定 JS 知识的人可以使用的提示.据我所知，从 Shiny-0.5 开始，您只能通过编写一些 Javascript/JQuery 来实现这一点.

This is a partial answer, giving you some pointers that anyone with some JS knowledge can use. To the best of my knowledge, as of Shiny-0.5, you can achieve this only by writing some Javascript/JQuery.

如果您能够将 JQuery 插件合并到您的 UI.R Shiny 应用程序中，这个链接 有你想要的.

If you are able to incorporate JQuery plug-ins into your UI.R Shiny app, this link has what you want.

1. 使用 CSS 样式确保 SliderInput 标签按照您想要的方式进行格式化.(显示日期/时间而不是数字.)我通常将任何 tags$head() 样式代码放在 SideBarPanel() 中，并且它起作用了.

1. Use CSS style to make sure that the SliderInput labels get formatted the way you want. (Showing Date/Time as opposed to numbers.) I typically put any tags$head() styling code inside SideBarPanel() and it has worked.

您还需要一个 Javascript 函数，它接受 input$number 并返回一个有效的日期/时间.代码链接: 这篇 JQuery 帖子 有一个你应该可以使用的 javascript 函数(使用 DatePicker)

You will also need a Javascript function that takes in the input$number and returns a valid date/time. Link with code: This JQuery post has a javascript function that you should be able use (with DatePicker)
