Overview

About

Maintained by Magnus Dehli VigelandCRAN page ↗GitHub ↗Issues ↗

Forensic applications of pedigree analysis, including likelihood ratios for relationship testing, general relatedness inference, marker simulation, and power analysis. 'forrel' is part of the 'pedsuite', a collection of packages for pedigree analysis, further described in the book 'Pedigree Analysis in R' (Vigeland, 2021, ISBN:9780128244302). Several functions deal specifically with power analysis in missing person cases, implementing methods described in Vigeland et al. (2020) doi:10.1016/j.fsigen.2020.102376. Methods for checking pairwise relationships are described in Egeland and Vigeland (2025) doi:10.1016/j.fsigen.2025.103270. Data exchange with the 'Familias' software (Egeland et al. (2000) doi:10.1016/S0379-0738(00)00147-X) is supported through the 'pedFamilias' package.

Changes in 1.10.0

New function LRpowerPlot() for visualising simulated LR distributions under two competing hypotheses.
LRpower() and exclusionPower() (and the new LRpowerPlot()) now accept a named list of frequency vectors as markers, similarly to profileSim().
For unlinked markers, kinshipLR() now also returns lnLRtotal and lnLRperMarker. Similarly the output of LRpower() now includes log10LRperSim. These reduce the risk of numerical overflow and underflow.
powerPlot() has been renamed to MPpowerPlot(), to avoid confusion with the new LRpowerPlot() and to reflect its connection with missing person (MP) applications. The old name is retained with a message for backwards compatibility.
missingPersonIP() has a new argument true, taking values "missing" (default, corresponding to the previous behaviour) or "unrelated", for simulating LR distributions under either hypothesis.
expectedLR() no longer requires the input pedigree hypotheses to be connected.
For X-chromosomal markers, expectedLR() now checks that the target individuals have the same sex in all hypotheses.
The re-exported showInTriangle() has been removed; use ribd::showInTriangle() directly.

Install

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

install.packages("forrel", 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("magnusdv/forrel")

Development version from magnusdv/forrel. 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-forrel

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-forrel

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-forrel

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.
