Convert ClusteredNeuroVol to a base array

Ensures that clustered volumes dispatch through the `as.array` S4 generic and return dense arrays of cluster labels aligned to the underlying space.

Provides an `as.array` S4 method so sparse volumes can be coerced with the same syntax used for dense objects.

Usage

# S4 method for class 'ClusteredNeuroVol'
as.array(x, ...)

# S4 method for class 'SparseNeuroVol'
as.array(x, ...)

# S4 method for class 'SparseNeuroVec'
as.array(x, ...)

Arguments

x

A SparseNeuroVec object.

...

Additional arguments (currently ignored).

Value

A dense array of cluster ids.

A dense array with voxel values at their spatial locations and zeros elsewhere.

A dense 4D array with sparse values inserted at mask indices and zeros elsewhere.
