Generate a Pop-up box in R

Question

Is it possible to make a pop-up box appear to the user to input a value in R? I've put together a pair of lines that perform the equivalent function using readline, but is it possible to make the prompt appear somewhere other than the console? Thank you!

 library(svDialogs)
 ## Ask something...
 user <- dlgInput("Who are you?", Sys.info()["user"])$res

... gets me the following pop-up input box:

(Whatever value is in the box when you click 'OK' is, as you'd expect, assigned to the symbol user.)
