But mapping R to a SUV makes R sound too much like a car, which many  
people know how to drive.  That is, someone who knows how to drive a  
car pretty much knows how to drive an SUV.  The SUV analogy implies  
that someone who knows another computer languages, e.g C, perl, VB,  
Java, SQL, would be able to use R.  Unfortunately, that is in all  
likelihood not the case.  R has a rather specialized syntax it uses  
to manipulate data.  It's not like C or perl or VB or Java or SQL.   
So, knowing those languages helps a little but not much.

Because of that, I would say R is more like a helicopter, a HUEY  
perhaps.
