as.rpart: Convert an E2Tree Object to rpart Format

In e2tree: Explainable Ensemble Trees

Convert an E2Tree Object to rpart Format

Description

Coerces an e2tree object into an rpart object, which can then be used with standard rpart methods for printing, plotting (e.g., via rpart.plot), and prediction.

Usage

as.rpart(x, ...)

## S3 method for class 'e2tree'
as.rpart(x, ensemble, ...)

Arguments

x	An e2tree object.
...	Additional arguments (ignored).
ensemble	The ensemble model used to build the E2Tree. Supported classes: randomForest, ranger, xgb.Booster, lgb.Booster, gbm, catboost.CatBoost.

Value

An rpart object.

Examples

data(iris)
smp_size <- floor(0.75 * nrow(iris))
train_ind <- sample(seq_len(nrow(iris)), size = smp_size)
training <- iris[train_ind, ]

ensemble <- randomForest::randomForest(Species ~ ., data = training,
  importance = TRUE, proximity = TRUE)
D <- createDisMatrix(ensemble, data = training, label = "Species",
  parallel = list(active = FALSE, no_cores = 1))
setting <- list(impTotal = 0.1, maxDec = 0.01, n = 2, level = 5)
tree <- e2tree(Species ~ ., training, D, ensemble, setting)

rpart_obj <- as.rpart(tree, ensemble)
