Is it accidental or on purpose that names get stripped from the result of "cumsum", "cumprod", "cummin" and "cummax"? If it is accidental, I suggest that keeping names (and other attributes) would be appropriate. (Found porting code from S-PLUS.)

(Found porting code from S-PLUS.)Names, sure. I am not so sure about all other attributes, in particular class (suppose these were difftimes?). -- Brian D.

Given this counter-example, I would find it hard to argue that anything beyond names should be saved.
