Overview

About

Maintained by Cristiane TanigutiFirst published 2025-05-012 releasesCRAN page ↗GitHub ↗

Provides functions for estimating ploidy levels and detecting aneuploidy in individuals using allele intensities or allele count data from high-throughput genotyping platforms, including single nucleotide polymorphism (SNP) arrays and sequencing-based technologies. Implements method described in Taniguti et al. (2025) doi:10.1002/tpg2.70044 an extended version of the 'PennCNV' signal standardization method by Wang et al. (2007) doi:10.1101/gr.6861907 for higher ploidy levels. Computes B-allele frequencies (BAF), z-scores, and identifies copy number variation patterns.

Install

R (CRAN)pak (dev)Ubuntu (r2u)

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

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

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-qploidy

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled.

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