Functions to better visualize BRT outputs

The following functions allow visualization of various aspects of GBM gradient boosted regression tree outputs

tree_plot

• Creates a tree of histograms showing partitioning of data through a single tree within the model
• Only able to plot 6 splits Example:

sankey_tree

• Uses a sankey diagram to visualize data partitioning through a single tree in the model
• Can view all splits Example:

aggregate_split_sankey

• Aggregates all splits and following splits to show the most common split variables and the following split
• Option to exclude terminal nodes Example:

aggregate_tree_sankey

• Aggregates all trees throughout the model organized by split row to show typical patterns among split variables Example:
