R: Access to metadata elements

$.niftiImage {RNifti} | R Documentation

## Access to metadata elements

### Description

These methods provide shorthand access to metadata elements from the NIfTI header corresponding to an image. The extraction version returns the corresponding element from the result of `niftiHeader`, while the replacement version calls `asNifti` to replace it.

### Usage

    ## S3 method for class 'niftiImage'
    x$name

    ## S3 replacement method for class 'niftiImage'
    x$name <- value

### Arguments

`x` | A `"niftiImage"` object, internal or otherwise.
`name` | A string naming the field required.
`value` | A new value for the field.
