Arbor performs an analysis based on Recursive Partitioning Trees.  
This package was initially created on 2006-06-22 from the rpart 
library by Terry Therneau.  The package is maintained by TIBCO Software Inc.
and runs in the Spotfire S+ environment. The package includes methods for fitting
classification and regression trees. This is the Spotfire S+ version
of the package, renamed arbor to avoid conflicts with the
original code from the Mayo Clinic.
