igraph (version 1.3.5)

make_tree: Create tree graphs

Description

Create a k-ary tree graph, where almost all vertices other than the leaves have the same number of children.

Usage

make_tree(n, children = 2, mode = c("out", "in", "undirected"))
tree(...)

Value

An igraph graph

Arguments

n

Number of vertices.

children

Integer scalar, the number of children of a vertex (except for leafs)

mode

Defines the direction of the edges. out indicates that the edges point from the parent to the children, in indicates that they point from the children to their parents, while undirected creates an undirected graph.

...

Passed to make_tree or sample_tree.
