singleseqgset is a package for gene set enrichment analysis for single-cell RNAseq data. It uses a simple underlying statistic (variance inflated Wilcoxon rank sum testing) to determine enrichment of gene sets of interest across clusters. Check out the vignette for more information on the implementation.
You can install the development version of singleseqgset from github using devtools:
library(devtools)
install_github("arc85/singleseqgset")
library(singleseqgset)
