get_order: Getting an Integer Permutation Vector from a Permutation Object

Description

Method to get an integer permutation vector from an object of class ser_permutation or ser_permutation_vector.

Usage

get_order(x, ...)
## S3 method for class 'ser_permutation_vector':
get_order(x, \ldots)
## S3 method for class 'ser_permutation':
get_order(x, dim = 1, \ldots)
get_rank(x, ...)

Arguments

x

an object of class ser_permutation or ser_permutation_vector.

dim

which dimension should be returned?

...

further arguments (unused).

Value

• Returns an integer vector.

Details

get_order returns the seriation order as a permutation vector (index of 1st object, 2nd object, ... $n$th object). get_rank returns the seriation as a vector indicating the rank of the objects $1, 2, \dots, n$.
