Print terminal node x-region boundaries
treesum(tree, nodes = NULL)No return value (invisble NULL)
model object output from contrast() or prune()
vector of terminal node identifiers for the tree specifying the desired regions. The default is all terminal nodes.
The predictor variable x-boundaries defining each terminal node are printed.
For numeric variables: variable | sign | value
sign + => value=lower boundary on variable
sign - => value upper boundary on variable
For categorical variables: cat variable | sign | set of values
sign + => values in node
sign - => values not in node (compliment values in node) graphical representations of terminal node contrasts depend on the tree type
