How do you control the window size using javascript?

[Kylie]

Hey guys.
Im just playing around here with a website for http://www.mad-gamers.com and I was wondering how possible it is to control the size of the browzer window using a javascript code.
I might be missing something in my books, but I cant seem to find anything.

Thanks in advance.

window.resizeTo( x, y );

or

window.resizeBy( x, y );
