[R] Command to input a variable value in real time

[nicholas.wray at ntlworld.com]

Hi  I am sure that there is a command in R which tells the prog to wait until
you have input a value for a variable, but for the life of me I can't find it.
 Searches on the net only seem to talk about inputting datasets etc, not about
real time single inputs. I'd be most grateful if anyone could point me in the
right direction

Thanks, Nick Wray
