Hi

I'm trying to create a class. However, I've some problems...

I am used to program php. There I can create a new object and call a specific
function of this object. In R, I hoped to create a class similar and then
call the function like:

Creating the Class:
<CODE>-----------------------------------
setClass("connect",
		representation(test="function"))
)

setMethod("test", "connect", 
    function(value){ 
        value /2
	}
)
</CODE>-----------------------------------


testObj = new ("connect")
testObj at test(44)

That should return 22. However, unfortunately it does not work. How can I
solve this problem. I read several instructions, but how does R work???.
Does anybody have a very simple example like above.

I highly appreciate any help.
Thanks a lot.
Nik
