Rindex.
An index that can be used with any R-vector x of length n needs to store the original values together with the original positions, i.e. list (val=x, pos=order (x)), thus requires -- strongly simplified -- 2 ∗ n RAM. If we store this information in a binary tree, each value pair {val,pos} is stored in its own node together with two pointers ...
