\title{Create tree graphs}
\usage{
make_tree(n, children = 2, mode = c("out", "in", "undirected"))

tree(...)
}
\arguments{
\item{n}{Number of vertices.}

\item{children}{Integer scalar, the number of children of a vertex
(except for leafs)}

\item{mode}{Defines the direction of the
edges. \code{out} indicates that the edges point from the parent to
the children, \verb{in} indicates that they point from the children
to their parents, while \code{undirected} creates an undirected
graph.}

\item{...}{Passed to \code{make_tree()} or \code{sample_tree()}.}
}
\value{
An igraph graph
}
\description{
Create a k-ary tree graph, where almost all vertices other than the leaves
have the same number of children.
