Produce density plots of iPAS permutation scores for a given pathway for multiple experiments

This function is the same as the iPAS_density function, except for all experiments at once. The function returns a plot of the probability density of the null distribution of iPAS scores for permutation signatures for a given pathway. The iPAS score for the (non-permuted) input signature is shown by a red bar.

iPAS_density_facet(
  res,
  score_type = c("z_score", "score"),
  path,
  fill = "light blue"
)

Arguments

res	output object from the iPAS_enrich function
score_type	the type of iPAS score to graph. "score" will show raw iPAS scores and "z_score" will show normalized iPAS scores.
path	the KEGG pathway ID of the pathway to graph (e.g. "hsa04150" for the mTOR pathway)
fill	the color to fill in the density plot, "light blue" by default.
