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.
