R: Write a NIfTI-1 format file

writeNifti {RNifti} | R Documentation

## Write a NIfTI-1 format file

### Description

This function writes an image to NIfTI-1 format, using the standard NIfTI-1 C library.

### Usage

    writeNifti(image, file, template = NULL, datatype = "auto")

### Arguments

`image` | An image, in any acceptable form (see `retrieveNifti`).
`file` | A character string containing a file name.
`template` | An optional template object to derive NIfTI-1 properties from. Passed to `updateNifti` if `image` is an array.
`datatype` | The NIfTI datatype to use when writing the data out. The default, `"auto"` uses the R type or, for internal images, the original datatype. Other possibilities are `"float"`, `"int16"`, etc., which may be preferred to reduce file size. However, no checks are done to ensure that the coercion maintains precision.
