Creating flow variables with an R Snippet

Hi,

I am new to Knime and I saw this previous post but could not get it to work.  When ever I applied this syntax to my R snippet, the flow variable does not get created (I checked the Node Monitor as well as the Flow Variable list). 

I would assume the following code should create a flow variable named "new" with a value of "Testing", but nothing seems to get created

knime.flow.out <- list(new = "Testing")

Any ideas on how to create flow variables via an R snippet?  Has the syntax changed? Am I just missing something really simple here?

Thanks!
