In oro.nifti: Rigorous - NIfTI+ANALYZE+AFNI Input / Output

Description

The NIfTI class for medical imaging data.

Objects from the Class

Objects can be created by calls of the form new("nifti", data, dim, dimnames, ...) or by calling the nifti function.

Methods

aux.file<-

signature(x = "nifti"): replaces the “auxiliary file” field

aux.file

signature(object = "nifti"): returns the “auxiliary file” field

descrip<-

signature(x = "nifti"): replaces the “description” field

descrip

signature(object = "nifti"): returns the “description” field

image

signature(x = "nifti"): diplays the image(s)

orthographic

signature(x = "nifti"): displays the image(s)

overlay

signature(x = "nifti", y = "nifti"): displays the image(s)

show

signature(object = "nifti"): prints out a summary of the imaging data
