| index-class {Matrix} | R Documentation |
The class "index" is a virtual class used for
indices (in signatures) for matrix indexing and sub-assignment of
"Matrix" matrices.
In fact, it is currently implemented as a simple class union
(setClassUnion) of
"numeric", "logical" and "character".
Since it is a virtual Class, no objects may be created from it.

Subassign-methods, also for examples.
