dim.internalImage | R Documentation |
An internal image is a simple R object with a few attributes including a
pointer to an internal C structure, which contains the full image data. They
are used in the package for efficiency, but can be converted to a normal
R array using the as.array
method. Attributes of these objects should
not be changed.
