atomicVector-class | R Documentation |

The `class`

`"atomicVector"`

is a
*virtual* class containing all atomic vector classes of base **R**,
as also implicitly defined via `is.atomic`

.

A virtual Class: No objects may be created from it.

In the Matrix package, the "atomicVector" is used in signatures where typically “old-style” "matrix" objects can be used and can be substituted by simple vectors.

The atomic classes
`"logical"`

, `"integer"`

, `"double"`

, `"numeric"`

,
`"complex"`

, `"raw"`

and `"character"`

are extended
directly. Note that `"numeric"`

already contains `"integer"`

and `"double"`

, but we want all of them to be direct subclasses of
`"atomicVector"`

.
