30 rpart.dist<br />
surrogatestyle<br />
controls the selection of a best surrogate. If set to 0 (default) the program uses<br />
the total number of correct classification for a potential surrogate variable, if<br />
set to 1 it uses the percent correct, calculated over the non-missing values of<br />
the surrogate. <strong>The</strong> first option more severely penalizes covariates with a large<br />
number of missing values.<br />
maxdepth<br />
Set the maximum depth of any node of the final tree, with the root node counted<br />
as depth 0 (past 30 rpart will give nonsense results on 32-bit machines).<br />
... mop up other arguments.<br />
Value<br />
a list containing the options.<br />
