isImage

object

The value to return if the function can't tell whether or not
the <code>object</code> is an image.

unsure


This function tried to determine whether an object is an image that the
package knows how to handle. If its class is <code>"nifti"</code>,
<code>"niftiImage"</code>, <code>"internalImage"</code> or <code>"MriImage"</code>, then the
result is always <code>TRUE</code>. Likewise if it has an internal image pointer.
If it has no <code>dim</code> attribute, or looks like an affine matrix, then the
result is <code>FALSE</code>. Otherwise the value of the <code>unsure</code> argument
is returned.


Provides an R interface to the NiftyReg image registration tools
<http://sourceforge.net/projects/niftyreg/>. Linear and nonlinear registration
are supported, in two and three dimensions.
