\begin{Description}\relax
Creates or tests for objects of type \code{"integer"}.\end{Description}
\begin{Usage}
\begin{verbatim}
integer(length = 0)
as.integer(x)
is.integer(x)
\end{verbatim}
\end{Usage}
\begin{Value}
\code{integer} creates a integer vector of the specified length.
Each element of the vector is equal to \code{0}.
Integer vectors exist so that data can be passed to C or Fortran code
which expects them.

\code{as.integer} attempts to coerce its argument to be of integer
type.

\code{is.integer} returns \code{TRUE} or \code{FALSE} depending on
whether its argument is of integer type or not.\end{Value}
