nbay13 / lsea

An R package for analyzing lipidomics data from the UCLA lipidomics lab

lsea

lsea is an R package for perfoming Lipid Structure Enrichment Analysis (LSEA) on combinations of lipid classes, chain lengths, and degrees of unsaturation.

Lipid sets for testing are assembled from the lipid species provided based on their LIPIDMAPS-style name. Name parsing is designed for results generated by the UCLA lipidomics lab.
