R tcltk：tkframe的标题

Question

I think this is a simple question but can't figure it out. I'm trying to build a frame and hoping I can add a title to it. For example, I like to create a slider in a frame. But to identify the frame I'd like to add a title to it. I have no reputation so I can't add a picture, but something like the word "title" below:

--- title --------------------------------

| ===[ ]=================== |

-----.-----------------------------------

Or:

How can I do it?

Answer 1

查看tcltk软件包中的ttklabelframe函数。

Answer 2

There is a package called rpanel, where somehow the frames are all titled. You might want to look into that one.
