YARF: Yet Another Random Forests Package

R-CMD-check pkgdown R-universe License: GPL-3

YARF—Yet Another Random Forests package—is a customizable, asynchronous, and parallelized random-forest implementation for R. It supports custom JavaScript splitting and aggregation behavior, missingness incorporated in attributes, and random-forest-based imputation.

Highlights

  • Classification and regression forests with out-of-bag diagnostics
  • Custom JavaScript split rules and aggregation functions
  • Missingness incorporated in attributes (MIA)
  • Random-forest-based missing-value imputation
  • Asynchronous and parallel tree construction
  • Variable-importance, interaction, proximity, and tree-inspection tools

Installation

YARF is distributed through the kapelner R-universe, not CRAN:

install.packages(
  "YARF",
  repos = c(
    kapelner = "https://kapelner.r-universe.dev",
    CRAN = "https://cloud.r-project.org"
  )
)

Java 8 or newer is required.

Quick start 

library(YARF)

fit <- YARF(
  X = iris[, 1:4],
  y = iris$Species,
  num_trees = 100
)

predict(fit, iris[, 1:4])

See the package website for the getting-started guide and reference, and the R-universe package page for builds and binaries.
