ser_permutation {seriation}

Class ser_permutation – A Collection of Permutation Vectors for Seriation

Description

The class ser_permutation is a collection of permutation vectors (see class ser_permutation_vector), one for each dimension (mode) of the data to be permuted.

Usage

ser_permutation(x, ...)

## S3 method for class 'ser_permutation'
print(x, ...)

## S3 method for class 'ser_permutation'
summary(object, ...)

## S3 method for class 'ser_permutation'
c(..., recursive = FALSE)

## S3 method for class 'ser_permutation'
object[i, ...]

Arguments

x, object

an object of class ser_permutation_vector or any object which can be converted into a object of class ser_permutation (e.g. an integer vector).

...

vectors for further dimensions.

recursive

ignored.

i

index of the dimension(s) to extract.

Value

An object of class ser_permutation.

Examples

o <- ser_permutation(1:5, 10:1)
o

## length (number of dimensions)
length(o)

## get permutation vector for 2nd dimension
get_order(o, 2)

## reverse dimensions
o[2:1]

## combine
o <- c(o, ser_permutation(1:15))
o

## get an individual permutation
o[[2]]

## reverse the order of a permutation
o[[2]] <- rev(o[[2]])
get_order(o,2)
