Overview

About

Maintained by Yannik SchermerFirst published 2025-09-015 releasesCRAN page ↗GitHub ↗

Facilitate tasks typically encountered during metabolomics data analysis including data import, filtering, missing value imputation (Stacklies et al. (2007) doi:10.1093/bioinformatics/btm069, Stekhoven et al. (2012) doi:10.1093/bioinformatics/btr597, Tibshirani et al. (2017) doi:10.18129/B9.BIOC.IMPUTE, Troyanskaya et al. (2001) doi:10.1093/bioinformatics/17.6.520), normalization (Bolstad et al. (2003) doi:10.1093/bioinformatics/19.2.185, Dieterle et al. (2006) doi:10.1021/ac051632c, Zhao et al. (2020) doi:10.1038/s41598-020-72664-6) transformation, centering and scaling (Van Den Berg et al. (2006) doi:10.1186/1471-2164-7-142) as well as statistical tests and plotting. 'metamorphr' introduces a tidy (Wickham et al. (2019) doi:10.21105/joss.01686) format for metabolomics data and is designed to make it easier to build elaborate analysis workflows and to integrate them with 'tidyverse' packages including 'dplyr' and 'ggplot2'.

Install

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

install.packages("metamorphr", 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("yasche/metamorphr")

Development version from yasche/metamorphr. 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-metamorphr

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
