In bbuchsbaum/neuroim2: Data Structures and IO for Neuroimaging Data with an Emphasis on Functional Magnetic Resonance Imaging (FMRI)

Array-like access for 3-dimensional data structures

Description

This generic function provides array-like access for 3-dimensional data structures. It allows for flexible indexing and subsetting of 3D arrays or array-like objects.

Usage

## S4 method for signature 'ArrayLike3D,numeric,missing,ANY'
x[i, j, k, ..., drop = TRUE]

## S4 method for signature 'ArrayLike3D,matrix,missing,ANY'
x[i, j, k, ..., drop = TRUE]

## S4 method for signature 'ArrayLike3D,missing,missing,ANY'
x[i, j, k, ..., drop = TRUE]

## S4 method for signature 'ArrayLike3D,missing,numeric,ANY'
x[i, j, k, ..., drop = TRUE]

Arguments

x	The 3-dimensional object to be accessed.
i	First index or dimension.
j	Second index or dimension.
k	Third index or dimension.
...	Additional arguments passed to methods.
drop	Logical. If TRUE, the result is coerced to the lowest possible dimension.

Value

A subset of the input object, with dimensions depending on the indexing and the 'drop' parameter.
