Overview

About

Maintained by R.Andres CastanedaCRAN page ↗GitHub ↗Website ↗Issues ↗

Tool for diagnosing table joins. It combines the speed of `collapse` and `data.table`, the flexibility of `dplyr`, and the diagnosis and features of the `merge` command in `Stata`.

Changes in 0.3.0

Breaking Changes

**Minimum R version:** Now requires R ≥ 4.2.0 (previously R ≥ 2.10.0) due to use of native pipe operator (|>) introduced in R 4.1.0 and uses the pipe placeholder syntax added in R 4.2.0. Users on R 4.0.x must upgrade to use this version.
**Default verbosity:** possible_ids.verbose default changed from TRUE to FALSE to reduce console output by default.

New Features

**Variable class validation:** New internal function check_var_class() validates that join (by) variables have supported classes (character, integer, numeric, factor, logical, Date, POSIXct, fs_path). Warns users when unsupported classes (e.g., list, complex, raw) are detected and suggests coercion.
**Variable filtering helper:** New filter_vars() function simplifies inclusion/exclusion of variables based on names or classes in possible_ids() and related functions.
**Test data helper:** New make_test_data() function provides standardized test datasets to improve test maintainability.

Improvements

**Zero-row input handling:** check_xy() now detects and reports when input tables have zero rows (previously would silently proceed).
**Enhanced by expression support:** Improved handling of by expressions (e.g., "x == y"). Temporary keys are now created only when necessary, and original column names are preserved when possible, reducing unnecessary data.table modifications.
**CI/CD updates:** GitHub Actions workflow upgraded from upload-artifact@v3 to v4 for better compatibility.

**Dependencies:** Added glue package to Imports for improved string interpolation in messages.

Bug Fixes

**Test suite improvements:** Rewrote and expanded test coverage in test-checks.R to use helper data and explicit expectations. Added error tests for unsupported by variable types and formats.
**Documentation updates:** Added complete documentation for check_var_class(), filter_vars(), and other internal helpers. Updated man/possible_ids.Rd to reflect new default parameter values.
**Code formatting:** Minor formatting improvements throughout codebase for consistency.

From NEWS.md in the release

Install

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

install.packages("joyn", 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("randrescastaneda/joyn")

Development version from randrescastaneda/joyn. 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-joyn

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-joyn

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-joyn

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.
