Does anyone know what the vertical line in the gseaplot from clusterProfiler represents?

I saw in the help page that it indicates the maximum/minimal running enrichment score. But does anyone know more details about its calculation and meaning?

Cheers,

Abel

Which vertical line do you exactly refer to? See here for example of a gseaplot obtained from clusterProfiler.

The calculations and interpretation of the scores can be found (among others) here (PathwayCommons) or here (at the GSEA webpage).

2.4kThe equation of a vertical line does NOT have a y-intercept on account that a vertical line in no way crosses the y-axis.

The slope of a vertical line is undefined due to the fact the denominator of the slope (the exchange in X) is 0

Vertical strains assist determine if a relation is a feature in math.

The equation of a vertical line continually takes the shape x = k

where ok is any wide variety and ok is also the x-intercept. For example inside the graph below, the vertical line has the equation x = 2 As you may see here within the picture underneath, the road is going straight up and down at x = 2
