R: Obtain an internal NIfTI representation of an object

retrieveNifti {RNifti} | R Documentation

## Obtain an internal NIfTI representation of an object

### Description

This function converts filenames, arrays and other image classes into an object of class `"internalImage"`.

### Usage

    retrieveNifti(object)

### Arguments

`object` | Any suitable object (see Details).

### Details

If the `object` has an internal NIfTI pointer, that will be retrieved directly. Otherwise, if it is a string, it will be taken to be a filename. If it looks like a `"nifti"` object (from package `oro.nifti`), or an `"MriImage"` object (from package `tractor.base`), a conversion will be attempted. A list will be assumed to be of the form produced by `niftiHeader`. Finally, a numeric array or matrix will be converted using default image parameters.

### Value

An internal image.
