Description

Finds the inverse of a permutation given as a vector of indices.

Usage

Arguments

i

a sequence of different integers in 1:n considered as a permutation given by p=unique(c(i,1:n))

n

the number of elements to be permuted

Details

The inverse permutation is defined by p[v]==1:n and v[p]==1:n.

Value

an integer vector v describing the inverse permutation of p.
