x |
character path of image or an object of class nifti, or array |
reorient |
(logical) passed to |
allow.array |
(logical) Are array types allowed (TRUE) or should there be an error if the object is not character or class nifti. |
fast |
if |
need_header |
if |
... |
additional arguments to pass to |
nifti object or array if allow.array=TRUE and x is an array
