library(randomPlantedForest)

# introduce factor variables to show categorical feature handling
mtcars$cyl <- factor(mtcars$cyl)
mtcars$vs <- factor(mtcars$vs)

# Fit forest, get components
set.seed(12)
rpfit <- rpf(mpg ~ cyl + wt + hp + drat + vs, data = mtcars, ntrees = 25, max_interaction = 3)
components <- glex(rpfit, mtcars)

# Get component object with only "hp" and its interactions
subset_components(components, "hp")

subset_component_names(components, "hp")
}
