\description{
Methods for \code{cbind} and \code{rbind} for hyperframes.
}
\usage{
\method{cbind}{hyperframe}(...)
\method{rbind}{hyperframe}(...)
}
\arguments{
\item{\dots}{
Any number of hyperframes (objects of class \code{\link{hyperframe}}).
}
}
\details{
These are methods for \code{\link{cbind}}
and \code{\link{rbind}} for hyperframes.
Note that \emph{all} the arguments must be hyperframes (because of
the peculiar dispatch rules of \code{\link{cbind}} and
\code{\link{rbind}}).
To combine a hyperframe with a data frame, one should either
convert the data frame to a hyperframe using
\code{\link{as.hyperframe}}, or explicitly invoke the
function \code{cbind.hyperframe} or \code{rbind.hyperframe}.
In other words: if \code{h} is a hyperframe and \code{d} is a data frame,
the result of \code{cbind(h,d)} will be the same as
\code{cbind(as.data.frame(h), d)}, so that all hypercolumns
of \code{h} will be deleted (and a warning will be issued).
To combine \code{h} with \code{d}
so that all columns of \code{h} are retained,
type either \code{cbind(h, as.hyperframe(d))} or
\code{cbind.hyperframe(h,d)}.
}
\value{
Another hyperframe.
