Array-like access for 4-dimensional data structures

This generic function provides array-like access for 4-dimensional data structures. It allows for flexible indexing and subsetting of 4D arrays or array-like objects.

Provides array-like access to ClusteredNeuroVec objects, supporting extraction patterns like x[,,,t] to get 3D volumes at specific time points.

Usage

# S4 method for class 'ArrayLike4D,matrix,missing,ANY'
x[i, j, k, m, ..., drop = TRUE]

# S4 method for class 'ArrayLike4D,numeric,numeric,ANY'
x[i, j, k, m, ..., drop = TRUE]

# S4 method for class 'ArrayLike4D,numeric,missing,ANY'
x[i, j, k, m, ..., drop = TRUE]

# S4 method for class 'ArrayLike4D,integer,missing,ANY'
x[i, j, k, m, ..., drop = TRUE]

# S4 method for class 'ArrayLike4D,missing,missing,ANY'
x[i, j, k, m, ..., drop = TRUE]

# S4 method for class 'ArrayLike4D,missing,numeric,ANY'
x[i, j, k, m, ..., drop = TRUE]

# S4 method for class 'ClusteredNeuroVec,missing,missing,ANY'
x[i, j, k, m, ..., drop = TRUE]

# S4 method for class 'ClusteredNeuroVec,missing,missing,ANY'
x[i, j, k, m, ..., drop = TRUE]

# S4 method for class 'ClusteredNeuroVec,numeric,numeric,ANY'
x[i, j, k, m, ..., drop = TRUE]

Arguments

x

The 4-dimensional object to be accessed.

i

First index or dimension.

j

Second index or dimension.

k

Third index or dimension.

m

Fourth 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.
