R help - Jul 2004 - Newbie

Hi, 

I wish build a R-script (or a  R-function) that read a number from the keyboard
and then process it.
For example: from R I load the function X, that ask me the level of confidence
"\alpha", by keyboard I write 5 and the function go on.

Thanks in advance

You don't say what operating system you're using .....

Anyhow, as far as I know there is no built-in to clear the screen.
But one is easy to build.  On a Unix system you could do

	cl <- function(){system("clear")}

then executing cl() will clear the screen for you.

On a Windoze system I think replacing ``clear'' by ``cls''
in the definition of cl() should work.
