Rails - Apr 2005 - How to set Collection selected value

I notice that:

options_from_collection_for_select(collection, value_method,
text_method, *selected_value = nil*)

has an argument to specify the selected entry; is it possible
to specify this using:

collection_select(object, method, collection, value_method, text_method,
options = {}, html_options = {})

?

Thanks,
Michael

Nevermind, I realised what''s going on.
