Dials for rpartScore engine parameters

These parameters are auxiliary to decision tree models that use the "rpartScore" engine. They correspond to tuning parameters that would be specified using set_engine("rpartScore", ...).

Usage

split_func(values = c("abs", "quad"))

prune_func(values = c("mr", "mc"))

Arguments

values

A character string of possible values.

Value

An object of S3 parent class param and primary class qual_param; see dials::new_qual_param().

Details

split_func and prune_func are dials for split and prune, respectively. See ?rpartScore::rpartScore for more details on the original parameters. These parameters are engine-specific, not general to decision tree models, so are provided here rather than in dials.
