calculate_pathway_gsea {clustifyr} | R Documentation |
Convert expression matrix to GSEA pathway scores (would take a similar place in workflow before average_clusters/binarize)
calculate_pathway_gsea( mat, pathway_list, n_perm = 1000, scale = TRUE, no_warnings = TRUE )
mat |
expression matrix |
pathway_list |
a list of vectors, each named for a specific pathway, or dataframe |
n_perm |
Number of permutation for fgsea function. Defaults to 1000. |
scale |
convert expr_mat into zscores prior to running GSEA?, default = FALSE |
no_warnings |
suppress warnings from gsea ties |
matrix of GSEA NES values, cell types as row names, pathways as column names
