\title{Wrapper For Applying Atomic Functions To Arrays.}
\usage{
Apply(data, input_margins = NULL, AtomicFun, ..., parallel = FALSE,
  ncores = NULL, margins = NULL)
}
\arguments{
\item{data}{A single object (vector, matrix or array) or a list of objects.}

\item{input_margins}{List of vectors containing the margins to be input to the function for each object. Or, if there is a single vector of margins specified and a list of objects in data, then the single set of margins is applied over all objects.}

\item{AtomicFun}{Function to be applied to the arrays.}

\item{...}{Additional arguments to be used in the AtomicFun.}

\item{parallel}{Logical, should the function be applied in parallel.}

\item{ncores}{The number of cores to use for parallel computation.}

\item{margins}{List of vectors containing the margins for the function to be applied over for each object in the data. Or, if there is a single vector of margins specified and a list of objects in data, then the single set of margins is applied over all objects.}
}
\value{
Array with dimensions equal to margins[[1]], and any additional dimensions resulting from AtomicFun.
}
\description{
A wrapper for applying a function across one or more arrays. The user can input one or more arrays, and specify the dimensions of each the arrays over which the function should be looped. This is a extension of the apply paradigm to the case where the data being considered is distributed across multiple objects.

\examples{
data = list(array(rnorm(1000), c(10,10,10)),array(rnorm(1000), c(10,10,10)))
margins = list(c(1, 3), c(1, 3))
corr <- Apply(data, margins, AtomicFun = "cor")
