\title{
Transposition of Sparse Array
}
\description{
Transpose a sparse three-dimensional array by permuting its dimensions.
}
\usage{
\method{aperm}{sparse3Darray}(a, perm = NULL, resize = TRUE, \dots)
}
\arguments{
\item{a}{
A sparse three-dimensional array (object of class \code{"sparse3Darray"}).
}
\item{perm}{
The subscript permutation vector, a permutation of the integers \code{1:3}.
}
\item{resize}{
Logical value specifying whether the dimensions and dimnames of the array
should also be adjusted, by permuting them according to the permutation.
}
\item{\dots}{
Ignored.
}
}
\details{
The function \code{\link[base]{aperm}} is generic. This is the method
for the class \code{"sparse3Darray"} of sparse three-dimensional
arrays.
}
\value{
Another sparse three-dimensional array
(object of class \code{"sparse3Darray"}).
