[R] Help on rpart

[white.denis@epamail.epa.gov]

rpart (and tree) do not fit a linear model at each node, merely a
threshold split.  See Alexander, W. P., and Grimshaw, S. D. (1996),
"Treed Regression," Journal of Computational and Graphical Statistics,
5, 156-175, for an alternative that may meet your needs.
