\Header{any}{Are Some Values True?}
\keyword{logic}{any}
\begin{Description}\relax
Given a set of logical vectors, are any of the values true?
\end{Description}
\begin{Usage}
\begin{verbatim}
any(..., na.rm = FALSE)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{...}] one or more logical vectors.
\item[\code{na.rm}] logical. If true \code{NA} values are removed before
the result is computed.
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
This is a generic function: methods can be defined for it
directly or via the \code{\Link{Summary}} group generic.
\end{Details}
\begin{Value}
Given a sequence of logical arguments, a logical value indicating
whether or not any of the elements of \code{x} are \code{TRUE}.

The value returned is \code{TRUE} if any the values in \code{x}
are \code{TRUE}, and \code{FALSE} if all the values in \code{x}
are \code{FALSE}.

If \code{x} consists of a mix of \code{FALSE} and \code{NA} values,
the value is \code{NA}.
\end{Value}
