Question

How can we a design a dialog box in R?

In my mind I have something in which an alert message is displayed or where we can write a certain value and then clicking a button it performs some computation… is that possible within the R workspace?

Answer 1

Something like this should work

library("tcltk")
button <- tkmessageBox(title='Message',message='Error x!',type='ok')
button <- tclvalue(button)
if(button == 'ok'){
  #do something
}
