Helper function to get the plot data for GSEA plots

Usage

get_gsea_enrichment_data(
  stats,
  pathways,
  pathways_of_interest,
  gsea_results = NULL,
  gsea_param = 1
)

stats: Named numeric vector. The gene level statistic.
pathways: List. A named list with each element containing the genes for this pathway.
pathways_of_interest: String vector. Names of the pathways to plot. These strings need to be represented in the names of pathways.
gsea_results: Optional data.table with the bixverse GSEA results. If provided, the FDR and NES for the given pathway of interest will be also added to the plot.
gsea_param: Numeric. Defaults to 1.

A named list of gsea_par_plot_data objects, one per pathway that survived the size filters. Each one is a list with the following elements:

curve_dt - data.table with the running enrichment score, columns rank and ES.
ticks_dt - data.table with the positions of the pathway genes, columns rank and stat.
stats_dt - data.table with the ranked statistic, columns rank and stat.
key_points - Named numeric with pos_es, neg_es and spread_es, plus nes and fdr if gsea_results was provided.
additional_label - String or NULL. The NES/FDR annotation.
