## Not run: 
library(ranger)
set.seed(1234)
train.idx <- sample(nrow(iris), 2/3 * nrow(iris))
iris.train <- iris[train.idx, ]
iris.test <- iris[-train.idx, ]
rg.iris <- ranger(Species ~ ., data = iris.train)
pred.iris <- predict(rg.iris, data = iris.test, type = "terminalNodes")
 iris_dist <- predicted_forest_distance_parall(
   forest = rg.iris,
   predictions = pred.iris)
