Description Objects from the Class See Also Examples

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.

`[-methods`

, and
`Subassign-methods`

, also for examples.
