\title{Virtual Class "atomicVector" of Atomic Vectors}
\description{
The \code{\link{class}} \code{"atomicVector"} is a
\emph{virtual} class containing all atomic vector classes of base \R,
as also implicitly defined via \code{\link{is.atomic}}.
}
\section{Objects from the Class}{A virtual Class: No objects may be created from it.}
\section{Methods}{
In the \pkg{Matrix} package, the "atomicVector" is used in signatures
where typically \dQuote{old-style} "matrix" objects can be used and
can be substituted by simple vectors.
}
\section{Extends}{%% FIXME: promptClass() should show the direct subclasses !
The atomic classes
\code{"logical"}, \code{"integer"}, \code{"double"}, \code{"numeric"},
\code{"complex"}, \code{"raw"} and \code{"character"} are extended
directly. Note that \code{"numeric"} already contains \code{"integer"}
and \code{"double"}, but we want all of them to be direct subclasses of
\code{"atomicVector"}.
