The NIfTI class for medical imaging data.
Objects can be created by calls of the form new("nifti", data,
dim, dimnames, ...)
or by calling the nifti
function.

signature(x = "nifti")
: replaces the
“auxiliary file” field
signature(object = "nifti")
: returns the
“auxiliary file” field
signature(x = "nifti")
: replaces the
“description” field
signature(object = "nifti")
: returns the
“description” field
signature(x = "nifti")
: diplays the image(s)
signature(x = "nifti")
: displays the image(s)
signature(x = "nifti", y = "nifti")
: displays
the image(s)
signature(object = "nifti")
: prints out a summary
