investigate_signature: Investigate a given DGE dataset

Description Usage Arguments Value Examples

View source: R/investigate_signature.R

Description

This function takes a DGE Data frame and then finds concordant signatures to that. This generates an L1000 signature from the DGE dataset and then uploads that signature to iLINCS to find the relevant concordant (or discordant) signatures
