Preranked metric ties

[ToledoEM]

Hi, great package. I am wondering how it is manage when the metric of the ranked genes it is a tie, this for values not equal to 0.

The Broad Institute java software has a warning about this, but I did not find any information about it in the preprint nor the vignette.

Should ties be solve with jittering the duplicated values? or a warning be printed when there are ties in the ranked gene list?
