slices-methods: Extract an ordered series of 2D slices from a 3D or 4D object

In bbuchsbaum/neuroim2: Data Structures for Brain Imaging Data

Extract an ordered series of 2D slices from a 3D or 4D object

Description

This function extracts an ordered series of 2D slices from a 3D or 4D object. The returned slices are in the order they appear in the original object.

Usage

slices(x, ...)

## S4 method for signature 'NeuroVol'
slices(x)

Arguments

x	A NeuroVol object
...	Additional arguments to be passed to the underlying methods

Value

A list of 2D matrices, each containing a slice from the input x.

A deflist object containing functions that return 2D slices of the volume along the z-axis. The length of the deflist equals the number of slices in the z dimension.

Examples

# Create a simple 3D volume
space <- NeuroSpace(c(10,10,10), c(1,1,1))
vol <- NeuroVol(array(rnorm(10*10*10), c(10,10,10)), space)

# Get all slices along the z-axis
slc <- slices(vol)

# Number of slices equals the z dimension
length(slc) == dim(vol)[3]

# Each slice is a 2D matrix
dim(slc[[1]]) == c(10,10)
