Thanks, Andy. Let me ask a little more about the DUP argument. In the manual, I can see that only reference copy happens when passing an array, if DUP=FALSE. Then, what happens when returning it in a list, if DUP=FALSE? Another reference copy, or deep copy?
I am trying to implement a dynamic modeling system in R, where some C functions should be called more than 1000 times with arguments of huge arrays. So, the issue is important for better performance.
