Sweet! I didn't know about "with". I think that would do just fine.
Though I must say that when working in console mode, attach and  
detach are extremely convenient.

Are those  standard statistics terms? In that case,

I'm basically trying to make it so that someone not knowing the  
command names in R, and the order and names of all the parameters,  
but knowing what statistics they want to do, would be able to find  
them in the snippet menu. That's the one side to it. The other is  
simply saving typing time.

Well, "lines" creates a sequence of joined line segments. I would  
call that a polygonal line (not a polygon, which would be a closed  
such line).
