\usage{
unbranch(dend, ...)
\method{unbranch}{default}(dend, ...)
\method{unbranch}{dendrogram}(dend, branch_becoming_root = 1, new_root_height, ...)
\method{unbranch}{hclust}(dend, branch_becoming_root = 1, new_root_height, ...)
\method{unbranch}{phylo}(dend, ...)
}
\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")
dend <- as.dendrogram(hc)
par(mfrow = c(1, 3))
plot(dend, main = "original tree")
plot(unbranch(dend, 1), main = "unbranched tree (left branch)")
plot(unbranch(dend, 2), main = "tree without (right branch)")
