Given a GRanges dataset representing genes, will add an arbitrary value for them to be plotted in the Y axis without overlapping each other.
addStepping(genesDat, coordinates, mcol.name)
| genesDat | GRanges object containing gene information. |
|---|---|
| coordinates | GRanges object with coordinates you want to plot. |
| mcol.name | Integer containing the column number that contains the gene name. |
Calculates the stepping position to avoid overlap between genes.
