Overview

About

Maintained by Imad El BadisyCRAN page ↗GitHub ↗Issues ↗

Provides functional tools such as fmap(), fwalk(), and fapply() to iterate over vectors, data frames, or grouped data with optional parallelism and real-time progress tracking. Progress updates now reflect completed tasks across sequential, multicore, and cluster-backed execution. Designed for readable and reproducible workflows, including support for Monte Carlo simulations and benchmarking.

Changes in 0.5.1

Removed the stray LazyData: true field (the package ships no data/ directory, so it triggered an "Omitted 'LazyData'" note at build time).
Wrapped long example lines in floop(), fmapc(), fmapg(), fmapn(), and frepeat() that were overflowing the PDF manual's page width and triggering a LaTeX WARNING under R CMD check --as-cran.
Simplified DESCRIPTION's Description: field: dropped a stray cross-reference to another package by name and a GitHub link (URL/ BugReports already cover that).
Standardized Authors@R family-name casing and split URL/BugReports so URL holds only the CRAN package page and BugReports only the GitHub issues page, matching the pattern used across all packages.
Fixed fapply() and fmap() progress reporting so sequential, multicore, and cluster-backed execution advance on completed tasks rather than internal chunk boundaries.

Show all changes in 0.5.1Hide the rest of the changes in 0.5.1

Improved progress-bar output stability when user code emits messages during tracked execution.
Added progress-system regression tests covering sequential timing, exact parallel counts, and error propagation in cluster and multicore execution.
Updated package documentation to describe completion-driven progress semantics.

Install

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

install.packages("functionals", 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("ielbadisy/functionals")

Development version from ielbadisy/functionals. 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-functionals

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-functionals

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-functionals

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.
