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

- 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.
