Overview

About

Maintained by Henrik BengtssonCRAN page ↗GitHub ↗Website ↗Issues ↗

The futurize() function doi:10.48550/arXiv.2601.17578 turns sequential map-reduce functions such as base::lapply(), purrr::map(), 'foreach::foreach() %do% { ... }' into concurrent alternatives, providing you with a simple, straightforward path to scalable parallel computing via the 'future' ecosystem doi:10.32614/RJ-2021-048. By combining this transpiler function with R's native pipe operator, you have a convenient way for speeding up iterative computations with minimal refactoring, e.g. 'lapply(xs, fcn) |> futurize()', 'purrr::map(xs, fcn) |> futurize()', and 'foreach::foreach(x = xs) %do% { fcn(x) } |> futurize()'. Other map-reduce packages that can be "futurized" are 'BiocParallel', 'plyr', 'crossmap', 'pbapply' packages. There is also support for a growing set of domain-specific packages on CRAN (e.g. 'boot', 'caret', 'DiceKriging', 'ez', 'fgsea', 'fwb', 'gamlss', 'glmmTMB', 'glmnet', 'kernelshap', 'lme4', 'metafor', 'mgcv', 'modelsummary', 'parameters', 'partykit', 'pls', 'pvclust', 'riskRegression', 'rugarch', 'sandwich', 'seriation', 'shapr', 'Sim.DiffProc', 'SimDesign', 'stars', 'strucchange', 'SuperLearner', 'terra', 'tm', 'TSP', and 'vegan') and on Bioconductor (e.g. 'DESeq2', 'GenomicAlignments', 'GSVA', 'Rsamtools', 'scater', 'scuttle', 'SingleCellExperiment', and 'sva').

Changes in 1.1.0

Significant Changes

Futurizing foreach(..., .options.future = list(...)) %do% { ... } is now an error, because %do% never supported such options in the first place. Instead, pass future options to futurize(), e.g. foreach(...) %do% { ... } |> futurize(seed = TRUE). Previously, such attempts were silently ignored.
Futurization of **GSVA** functions will stop working with **GSVA** (>= 2.7.0).

New Transpilers

Add support for domain-specific CRAN package **terra**, e.g. res <- tile_apply(r, function(x) x * 2) |> futurize().

New Features

Show all changes in 1.1.0Hide the rest of the changes in 1.1.0

futurize() now unwraps withCallingHandlers(), e.g. withCallingHandlers(lapply(xs, fcn), warning = ...) |> futurize().
Futurization of **lme4** functions now uses parallel = "future" available in **lme4** (>= 2.0-6). Older versions are still supported.

Bug Fixes

Option chunk_size was ignored when futurizing times(n) %do% { ... }.
Futurize option packages would drop packages that the transpiler declares as required on parallel workers.
Futurizing a call that specifies an argument that futurize() sets, e.g. bplapply(xs, fcn, BPPARAM = SerialParam()), or boot(..., parallel = "multicore"), gave an obscure error message. Now it gives an informative error.
Futurizing a call to an S3 or S4 generic function, whose first argument is a function call, e.g. influence(lmer(...)) |> futurize(), would evaluate that first argument twice; once to identify the method to be called, and once more when calling it. Now it is evaluated only once.
Attempts to futurize a generic function that dispatches to an unsupported S3 or S4 method gave an uninformative error message, e.g. summary(fit) |> futurize() and, with **BiocGenerics** attached, lapply(x, fcn) |> futurize() for an **S4Vectors** List. Now the error message names the method, its package, and the class dispatched on.
Attempts to futurize a function not part of a package gave an obscure error message suggestion to install a non-existing package.
Attempts to futurize an expression that is not a function call, e.g. { x } |> futurize(), gave an obscure error message.
All futurize options, e.g. seed, packages, and label, were ignored when futurizing **BiocParallel** functions.
Futurizing **plyr** functions with argument .paropts gave an obscure error. Now the .paropts options are passed on as-is, unless they specify .options.future, which gives an informative error suggesting to pass such options to futurize() instead.
Futurizing **plyr** functions produced a "No parallel backend registered" warning when using a single parallel worker, e.g. plan(sequential).

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("futurize", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("futureverse/futurize")

Development version from futureverse/futurize. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-futurize

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-futurize

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-futurize

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
