[R] Using text put into a dialog box

[Greg Snow]

You may want to use tkwait.window(tt)

If the below is in a function, then tkwait.window(tt) will wait until the window goes away (the user clicking on the button) before continuing with the code, then you can return the result after that.

Hope this helps,
