R: Permutation of indices and storage sequence of a tensor

reorder.tensor

R Documentation

Permutation of indices and storage sequence of a tensor

Description

This permutes tensor dimensions like aperm. However the interface is more flexible since not all dimensions have to given and names can be used instead of numbers.

Usage

## S3 method for class 'tensor'
reorder(x,i=NULL,...,by=NULL)

Arguments

`x`	the tensor
`i`	numeric or character giving dimensions intended to come first
`...`	further arguments to other instances of the generic function
`by`	the complement of i, if i is not given

Details

the remaining dimensions keep their relative sequence and follow at the end of the dimension attribute.

Value

reorder.tensor returns a tensor equal to x but stored with a different sequence of dimensions.

Examples

A <- to.tensor(1:20,c(A=2,B=2,C=5))
A
reorder(A,"C")
reorder(A,"B")
