\title{Switch a dCST hierarchy to the "rare" view (explicit rare buckets)}
\usage{
expand.rare(csts)
}
\arguments{
\item{csts}{A \code{"linf.csts"} object produced by \code{\link{linf.csts}}
and optionally refined by \code{\link{refine.linf.csts}} /
\code{\link{refine.linf.csts.iter}}.}
}
\value{
A \code{"linf.csts"} object using the "rare" view.
}
\description{
Returns a copy of a \code{"linf.csts"} object with \code{cell.label} (and, if
present, \code{cst.levels}) replaced by the precomputed "rare" labeling.
This does not recompute dCSTs; it only switches between labelings already
stored in the object. This explicit rare-bucket view is the active labeling
used by \code{low.freq.policy = "pure"}.
