True, we to guess. My guess is that he wants:
ask {gtools}
R Documentation
Display a prompt and collect the user's responseDescription
Display a prompt and collect the user's response

Usage
ask(msg = "Press <RETURN> to continue: ")
So one plot would be sent to a graphics device, then ask(), then after  
response, add a line or points or ... (but not a new plot() or  
dev.new() command)

?dev.cur
?abline
?points
