6 Installation

featureMSEA implements Feature-Based Metabolite Set Enrichment Analysis — a method that performs functional interpretation directly from ranked mass spectrometry features, without requiring complete metabolite identification or an arbitrary significance threshold to preselect features.

Install the TidyMass dependencies first, then the featureMSEA package itself from GitHub:

# Install TidyMass dependencies first
remotes::install_gitlab("tidymass/masstools")
remotes::install_gitlab("tidymass/massdataset")
remotes::install_gitlab("tidymass/metid")

# Install featuremsea
remotes::install_github("tidymass/featuremsea")

Once installed, load all required packages at the start of each session:

library(masstools)
library(massdataset)
library(metid)
library(featuremsea)
