Visualize R program user input questions?

In my R program the user has to type in some inputs. I did this with

readline('Please give the numerical input')

Depending on the input, the program computes further things. My question, is it also possible to visualize the users questions a bit? With readline everything happens in the console. Can I bring it in a nice format to the plot window (for example with a box where user can type in the input and than the program goes on depending on the input)?

You may also want to consider two alternatives.

svDialogs

Package svDigalogs would enable you to create an input window realitvly quickly. The code:

require(svDialogs)
## Ask something...
user <- dlgInput("Who are you?", Sys.info()["user"])$res
if (!length(user)) { # The user clicked the 'cancel' button
  cat("OK, you prefer to stay anonymous!\n")
} else {
  cat("Hello", user, "\n")
}

would generate the following window:

Input window

Shiny

Not sure if you considered that but you could quickly put together a Shiny with console and some input field. You could build a dynamic UI element asking user for input, if needed.
