[Rd] Small inconsistency in help page unique - duplicated doesn't return indices.

[Joris Meys]

I read this in the help page of unique in 2.14.0, but I reckon it's
not changed yet in 2.14.1

Under the section 'see also' is mentioned :

    duplicated which gives the indices of duplicated elements.

Afaik duplicated doesn't return the indices but a logical vector. I
propose to change to

    duplicated which gives a logical vector indicating duplicated elements.

or something along that line.

Cheers
Joris
