 `fgsea` is an R-package for fast preranked gene set enrichment analysis (GSEA). This package allows to quickly and accurately calculate arbitrarily low GSEA P-values for a collection of gene sets. P-value estimation is based on an adaptive multi-level split Monte-Carlo scheme. 
 See [the preprint](https://www.biorxiv.org/content/10.1101/060012v3) for algorithmic details.
