buildDT builds a model using the rpart function
from the rpart package.
buildDT(object, top = 0, ...)An ExprsArray object. The training set.
A numeric scalar or character vector. A numeric scalar indicates
the number of top features that should undergo feature selection. A character vector
indicates specifically which features by name should undergo feature selection.
Set top = 0 to include all features. A numeric vector can also be used
to indicate specific features by location, similar to a character vector.
Arguments passed to the detailed function.
Returns an ExprsModel object.
Provide cp as a numeric scalar to trim the rpart decision tree.
If provided, this argument is passed to the rpart::prune function.
Set cp = 0 to skip pruning (default behavior).
