Maintained by Wonseok OhFirst published 2026-08-041 releasesCRAN page ↗GitHub ↗

Supports matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry workflows from raw Bruker spectra to cohort-level peak matrices. Provides spectrum loading, Savitzky-Golay smoothing, baseline correction (SNIP and TopHat), Gaussian kernel-regression-based peak detection including shoulder peaks, peak-quality assessment, filtering, and cohort feature analysis. Computationally intensive routines are implemented in C++ using 'Rcpp'. The implemented signal-processing methods include those described by Savitzky and Golay (1964) doi:10.1021/ac60214a047, Ryan et al. (1988) doi:10.1016/0168-583X(88)90063-8, Stanford, Bagley and Solomon (2016) doi:10.1186/s12953-016-0107-8, and Nadaraya-Watson kernel regression (Nadaraya (1964) doi:10.1137/1109020; Watson (1964) https://www.jstor.org/stable/25049340).

Install

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

install.packages("MALDIassist", 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("hiows/MALDIassist")

Development version from hiows/MALDIassist. Installs pak first if it is not already available.

# 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-MALDIassist

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-MALDIassist

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed).
