'singscore' is an R/Bioconductor package which implements the simple single-sample gene-set (or gene-signature) scoring method proposed by Foroutan et al. (2018). It uses rank-based statistics to analyze each sample's gene expression profile and scores the expression activities of gene sets at a single-sample level.

These instructions will get you to install the package up and running on your local machine. If you experience any issues, please raise a GitHub issue at https://github.com/DavisLaboratory/singscore/issues.

# build_vignettes = TRUE to build vignettes upon installation
if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")
BiocManager::install("singscore")

The package comes with a vignette showing how the different functions in the package can be used to perform a gene-set enrichment analysis on a single sample level. Pre-built vignettes can be accessed via Bioconductor or the GitHub IO page.

A detailed workflow on using singscore to analyse the TCGA acute myeloid leukemia (AML) data is available as part of the SingscoreAMLMutations R/Bioconductor package.
