plotEnrichment ranks labels

[igordot]

Is it possible to add an option to add ranks labels to plotEnrichment()? Currently, it is not possible to determine the ranks order from the plot without some additional information. For example, if you are comparing KO to WT, it would be helpful add "KO" and "WT" to opposite ends of the X (ranks) axis.

Here is an example from limma::barcodeplot() to illustrate what I am trying convey:

If that is outside the scope of this package, do you have any suggestions on how to best add something like that with least interference with other elements?

Hi, it's a good question. I wasn't able to quickly find an easy way to do this. You can try to modify the plot yourself, as plotEnrichment function returns ggplot object.

Additionally, you can use fgsea::plotEnrichment function source code as a template, and make your own function.
