gsi2.invperm {compositions} | R Documentation |
Finds the inverse of a permutation given as a vector of indices.
gsi2.invperm( i,n )
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 |
The inverse permutation is defined by p[v]==1:n
and
v[p]==1:n
.
an integer vector v describing the inverse permutation of p.
