Example Events+ shortcode arguments

Maybe I am being thick, but are there any examples of shortcodes being used for Events+ that include some arguments?

For example, I'd like to use the [eab_archive] shortcode on a page, but specify that it should show all the events over the next 8 weeks. I've tried the following but it doesn't work;

[eab_archive weeks="8" ]

Can you help me please?
