Is it possible to change the size of the LIve Agent chat window when it launches from a chat button?

I tried this example, https://dashboard.liveagentforsalesforce.com/support/Customization/how-to/80, but could not get it to work.  If this is the correct solution, could someone post a complete example of the javascript that goes into the website?  It doesn't have to actually work, but I might be missing some kind of syntax.

Thanks.
