1 Introduction

Matter 2 provides an updated and more robust C++ backend to matter objects, along with a completely new implementation of sparse arrays and new signal processing functions for nonuniform sparse signal data.

Originally designed as a backend for the Cardinal package, The first version of Matter was constantly evolving to handle the ever-increasing demands of larger-than-memory mass spectrometry (MS) imaging experiments. While it was designed to be flexible from a user’s point-of-view to handle a wide array for file structures beyond the niche of MS imaging, its codebase was becoming increasingly difficult to maintain and update.

Matter 2 was re-written from the ground up to simplify some features that were rarely needed in practice and to provide a more robust and future-proof codebase for further improvement.

2 Installation

Matter can be installed via the BiocManager package.

install.packages("BiocManager")
BiocManager::install("matter")

The same function can be used to update Matter and other Bioconductor packages.

Once installed, Matter can be loaded with library():

library(matter)
