Building Random Trees

Description

Utility function to make small directed acyclic graphs, using the data.tree package. Nodes are provided with randomly-selected numerical values.

Usage

make_val_tree(min_children = 1,
                     max_children = 4,
                     min_depth = 3,
                     values = 1:5,
                     fillcolor = "palegreen",
                     fontcolor = "black",
                     seed = NULL)

Arguments

min_children	Minimum number of children when node will not be a leaf.
max_children	Maximum number of children when node will not be a leaf.
min_depth	Nodes at less than this specified depth will not be leaves.
values	Numerical vector of possible values to associate with each node.
fillcolor	Fill color for nodes.
fontcolor	Fonot color for text showing node value and node name.
seed	Option to set the random seed.

Value

A tree object of class "Node" and "R6"
