To make R beep when you want to alert users about an error, simply type:
alarm()
or
cat("\a")
or
library(tcltk)
tkbell()
The sound is not that "alarming" though, as far as I know, it is the only way R beeps.

Tcl
with <> for "Tcl"
The message is correct. Make sure you have your volumne tuned up. The sound is just a short beep sound.
