aperm: Transposing an array-like object

In Bioconductor/BiocGenerics: S4 generic functions used in Bioconductor

Transposing an array-like object

Description

Transpose an array-like object by permuting its dimensions.

This is a multidimensional generalization of the t() operator used for 2D-transposition.

NOTE: This man page is for the aperm S4 generic function defined in the BiocGenerics package. See ?base::aperm for the default method (defined in the base package). Bioconductor packages can define specific methods for objects not supported by the default method.

Usage

aperm(a, perm, ...)

Arguments

a	An array-like object.
perm, ...	See ?base::aperm for a description of these arguments.

Value

A transposed version of array-like object a, with subscripts permuted as indicated by the perm vector.
