gProfiler_cellWeighted_Foldchange: Pathway enrichment for cwFold-changes

In DustinSokolowski/scMappR: Single Cell Mapper

Description

This function runs through each list of cell weighted Fold changes (cwFold-changes) and completes both pathway and transcription factor (TF) enrichment.

Usage

gProfiler_cellWeighted_Foldchange(
  cellWeighted_Foldchange_matrix,
  species,
  background,
  gene_cut,
  newGprofiler
)

Arguments

cellWeighted_Foldchange_matrix	Matrix of cell weighted Fold changes from the deconvolute_and_contextualize functions.
species	Human, mouse, or a charcter that is compatible with gProfileR.
background	A list of background genes to test against.
gene_cut	The top number of genes in pathway analysis.
newGprofiler	Using gProfileR or gprofiler2, (T/F).

Details

This function takes a matrix of cellWeighted_Foldchange and a species (human, mouse, or a character directly compatible with g:ProfileR). Before completing pathway analysis with g:ProfileR. Enriched pathways are stored in a list and returned.

Value

List with the following elements:

BP	gprofiler enrichment of biological pathways for each cell-type
TF	gprofiler enrichment of transcription factors for eachc cell-type.

                                       theSpecies = theSpecies)
