Overview

About

Maintained by Hirujan RangarajCRAN page ↗GitHub ↗Website ↗Issues ↗

A transparent, rule-based framework for detecting changes between successive data cuts of clinical trial datasets, classifying those changes into clinically meaningful categories, tracing user-defined data lineage, and assessing which downstream analyses and outputs may be affected. The package is designed to complement existing low-level data frame comparison tools by adding clinical-trial-specific classification, lineage and impact-assessment layers on top of deterministic comparison. The rule-based classification is similar in spirit to the data validation infrastructure of van der Loo and de Jonge (2021) doi:10.18637/jss.v097.i10.

Changes in 0.2.0

Added an analysis/output registry: td_output() and output_registry() declare analyses and outputs and their inputs, and add_outputs(), add_edges() and remove_edges() graft, extend or override a lineage graph.
Added lineage_from_metadata(), which derives a lineage graph from a \pkg{metacore} object (or equivalent metadata tables), with provenance and a review list for ambiguous or unparsed references. aliases resolve tokens that would otherwise be ambiguous or unknown, and overrides merge an analysis/output registry into the generated graph.
Added a "diffdf" comparison backend to compare_cut(), which delegates value comparison to the \pkg{diffdf} package and translates its output into a tdiff object (schema comparison remains built in).
Added a case-study vignette using public pharmaverseadam data.

Show all changes in 0.2.0Hide the rest of the changes in 0.2.0

as_register() now coerces key columns to character, fixing a failure when key columns were not character.
New records in visit-based datasets are classified as new_visit rather than new_assessment.
Added edge-case tests; package coverage now exceeds 90%.
Bumped GitHub Actions and added Codecov configuration.

Install

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

install.packages("trialdiff", 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("Hirujan-R/trialdiff")

Development version from Hirujan-R/trialdiff. 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-trialdiff

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-trialdiff

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-trialdiff

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.
