  ...)

\method{unbranch}{hclust}(dend, branch_becoming_root = 1, new_root_height,

}
\arguments{
\item{dend}{a dendrogram (or hclust) object}

\item{...}{passed on}

\item{branch_becoming_root}{a numeric choosing the branch of the root which will become the new root (from left to right)}

\item{new_root_height}{the new height of the branch which will become the new root.
If the parameter is not given - the height of the original root is used.}
}
\value{
An unbranched dendrogram
}
\description{
unbranch trees and merges the subtree to the parent node.

\examples{
hc <- hclust(dist(USArrests[2:9,]), "com")
