When I use the duplicated function, I often need to find both the duplicates and the original element that was duplicated. This can be accomplished with: duplicated(OBJECT) | duplicated(OBJECT, fromLast=TRUE) >From my perspective, an improvement in the duplicated function would be an >option that accomplishes this with a single call to the function. This could >either be: 1. a new option: all=TRUE (pick whatever name makes sense) 2. allowing fromLast to take a new value (e.g., NA, in the spirit of the xpd option in par()) If my suggestion would yield unintended consequences, it can certainly be ignored.
