DeconvoBuddies

The goal of DeconvoBuddies is to provide helper functions for the deconvolution process, as well as a paired dataset designed to test the performance of deconvolution arguments. The dataset is from Human DLPFC, and contains bulk RNA-seq, single nucleus RNA-seq, and estimated cell type proportions from RNAScope/IF.

Installation instructions

Get the latest stable R release from CRAN. Then install DeconvoBuddies using from Bioconductor the following code:

if (!requireNamespace("BiocManager", quietly = TRUE)) {
    install.packages("BiocManager")
}

BiocManager::install("DeconvoBuddies")

And the development version from GitHub with:

BiocManager::install("LieberInstitute/DeconvoBuddies")
