\title{Remove Tips in a Phylogenetic Tree}
+\description{
+ \code{drop.tip} removes the terminal branches of a phylogenetic tree,
+ possibly removing the corresponding internal branches.
+
+ \code{extract.clade} does the inverse operation: it keeps all the tips
+ from a given node, and deletes all the other tips.

\usage{
drop.tip(phy, tip, trim.internal = TRUE, subtree = FALSE,
- root.edge = 0, rooted = is.rooted(phy))
-extract.clade(phy, node, root.edge = 0)
+ root.edge = 0, rooted = is.rooted(phy), interactive = FALSE)
+extract.clade(phy, node, root.edge = 0, interactive = FALSE)
}
\arguments{
\item{phy}{an object of class \code{"phylo"}.}
\item{root.edge}{an integer giving the number of internal branches to
be used to build the new root edge. This has no effect if
\code{trim.internal = FALSE}.}
- \item{rooted}{a logical indicated whether the tree must be treated as
+ \item{rooted}{a logical indicating whether the tree must be treated as
rooted or not. This allows to force the tree to be considered as
unrooted (see examples).}
\item{node}{a node number or label.}
