\arguments{
  \item{name}{The object to detach.  Defaults to \code{search()[pos]}.

\description{
Detach a database, i.e., remove it from the \code{\link{search}()} patch
of available \R objects. Usually, this either a \code{\link{data.frame}}
which has been \code{\link{attach}}ed or a package which was required
previously.
}
\value{
The attached database is returned invisibly, either as
\code{\link{data.frame}} or as \code{\link{list}}.
