aperm.sparse3Darray: Transposition of Sparse Array

Description

Transpose a sparse three-dimensional array by permuting its dimensions.

Usage

# S3 method for sparse3Darray
aperm(a, perm = NULL, resize = TRUE, ...)

Value

Another sparse three-dimensional array (object of class "sparse3Darray").

Arguments

a

A sparse three-dimensional array (object of class "sparse3Darray").

perm

The subscript permutation vector, a permutation of the integers 1:3.

resize

Logical value specifying whether the dimensions and dimnames of the array should also be adjusted, by permuting them according to the permutation.
