How to create a pop-up warning that the script has come to an end?

Question

I would like to display on screen one pop-up notifying that the code just ran.

The only script I have, follows below, is the one that opens a command window.

system('CMD /C "ECHO O seu script chegou ao fim! && PAUSE"', 
        invisible=FALSE, wait=FALSE)

Answer 1

Another solution is to use the tcltk package. This package is already installed in R, although it does not appear in the CRAN package list.

require(tcltk)
tkmessageBox(title = 'Exemplo tcltk', message = 'Operação concluída!', type = 'ok')

As with the rpanel package, the session will be blocked. If you do not want to block, da para usar uma progressbar, do pacote utils.

 invisible(winProgressBar(title = "Concluido!", label = "Operação concluída!", initial = 1))

If the goal is to draw attention, you can also use the alarm() to make a sound.

install.packages("rpanel")

Now Voce can do something like:

rp.messagebox("Popup usando rpanel", title="Titulo criativo")

that on my pc will generate the following window:

Detail that this popup will block the session.
