Displaying decision and regression trees
display prints the tree models returned by
function. Depending of parameter
format the output is prepared for either screen or in dot format.
The model structure as returned by
The type of output, i.e., prepared for screen display or in dot language
The tree based models returned by function
CoreModel are visualized.
Only tree based models supported, including the trees which include other prediction models in their leaves.
Tree based models available are decision trees (obtained by using parameter
model="tree" in CoreModel),
and regression trees (with
Models in the leaves of decision trees
can be set using parameter
At the moment naive Bayes and kNN are available, for details see helpCore.
Models in the leaves of regression trees can be set using parameter
At the moment kNN, kernel regression, and several types of linear models are available,
for details see helpCore.
The output in dot language can be used with graphViz visualization software to create model visualization in various formats.
The method invisibly returns a printed character vector.
