quincunx

The goal of {quincunx} is to provide programmatic access to the Polygenic Score (PGS) Catalog, an open resource for polygenic scores and associated metadata describing their development and respective assessment.

Installation

Install {quincunx} from CRAN:

# Install from CRAN
install.packages("quincunx")

You can instead install the development version of {quincunx} by setting Ramiro Magno’s universe repository:

options(repos = c(ramiromagno = 'https://ramiromagno.r-universe.dev',
                CRAN = 'https://cloud.r-project.org'))

install.packages('quincunx')

Package name and hex sticker

The package name {quincunx} is another name for Galton Board, that so nicely exemplifies the Central Limit Theorem, which in turn is a key concept of genetics, namely, Fisher’s infinitesimal model… which leads us to Polygenic Scores, the key concept of the PGS Catalog.

The bird in the hex sticker is a Porphyrio porphyrio, an emblematic species native to the Ria Formosa Natural Park, which is a wildlife reserve surrounding the University of Algarve, where the authors are affiliated.
