mincIO.getSliceXYZ-methods: Methods to Get a Slice from a MincVolumeIO Object
In jnikelski/rmincIO: Package for reading and writing MINC2 files

Description Usage Arguments Details Value Methods Author(s) See Also Examples

This method retrieves a specific slice from a MincVolumeIO object, and uses it to instantiate a MincSlice object.

## S4 method for signature 'MincVolumeIO'
mincIO.getSliceX(mincVolume, sliceNo)

## S4 method for signature 'MincVolumeIO'
mincIO.getSliceY(mincVolume, sliceNo)

## S4 method for signature 'MincVolumeIO'
mincIO.getSliceZ(mincVolume, sliceNo)

`mincVolume`	The name of a MincVolumeIO object, most likely created via a call to `mincIO.readVolume`.
`sliceNo`	All slice numbers are 1-relative, ranging from inferior-to-superior (axial), left-to-right (sagittal), and posterior-to-anterior (coronal).

Although the data within the MincVolumeIO object can be manipulated directly via indexing into the 3 dimensional (xyz) structure, extracting a single slice permits visualization and may make modification somewhat more efficient.

A MincSlice object.

mincVolume = "MincVolumeIO": Only one method/signature.
