immunedeconv: An R repository from thyagoleal

an R package for unified access to computational methods for estimating immune cell fractions from bulk RNA sequencing data.

Basic usage

immunedeconv::deconvolute(gene_expression_matrix, "quantiseq")

where gene_expression_matrix is a matrix with genes in rows and samples in columns. The rownames must be HGNC symbols and the colnames must be sample names. The method can be one of

quantiseq
timer
cibersort
cibersort_abs
mcp_counter
xcell
epic

Installation

System requirements: R >= 3.5. Only linux is officially supported, but Mac/Windows should work, too.

Bioconda (Linux/MacOS only)

The easiest way to retrieve this package and all its dependencies is to use Anaconda. The installation typically completes within minutes.

Download Miniconda, if you don't have a conda installation already.
(Optional) create and activate an environment for deconvolution:

conda create -n deconvolution
conda activate deconvolution

Install the immunedeconv package

conda install -c bioconda -c conda-forge r-immunedeconv

conda will automatically install the package and all dependencies. You can then open an R instance within the environment and use the package.

Standard R Package

We highly recommend using conda, as it will avoid incompatibilities between different package versions. That being said, you can also install immunedeconv as a regular R package in your default R installation. The installation typically completes within 30 minutes, depending on how many dependency packages need to be compiled.

The easiest way to do so is to use the remotes package, which will automatically download all CRAN, Bioconductor and GitHub dependencies:
