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.
