`geneSets` | list of gene sets/pathways, each containing identifiers of genes contained in the set. E.g. pathways from Gene Ontology databases output from the `getGeneSetsForPlot` function or any custom list of pathways. The genes identifiers should correspond to the variable `geneSetsVar` contained in the phenoData, if not specified the featureNames are used. If several gene sets have the same name, they will be combine to extract the top gene sets.

`topGeneSets` | numeric indicating which percentile (if <=1) or number (if >1) of gene sets most distant to the origin of the plot to annotate, by default: 10 gene sets are selected If no gene sets should be annotated, set this parameter to 0.

`includeLineOrigin` | if TRUE (by default) include vertical line at x = 0 and horizontal line at y = 0
`typePlot` | type of the plot returned, either 'static' (static) or interactive' (potentially interactive)
`figInteractiveSize` | vector containing the size of the interactive plot, as [width, height] by default: c(600, 400). This is passed to the `width` and `height` parameters of: for rbokeh plots: the `bokeh::figure` function for ggvis plots: the `ggvis::set_options` function
`ggvisAdjustLegend` | logical, if TRUE (by default) adjust the legends in `ggvis` to avoid overlapping legends when multiple legends
`interactiveTooltip` | logical, if TRUE, add hoover functionality showing sample annotation (variables used in the plot) in the plot
`interactiveTooltipExtraVars` | name of extra variable(s) (in varLabels of the `eset`) to add in rbokehEsetPlot to label the samples, empty by default
`packageInteractivity` | if `typePlot` is 'interactive', package used for interactive plot, either 'rbokeh' (by default) or 'ggvis'
`returnTopElements` | logical, if TRUE return also the top elements
`returnEsetPlot` | logical, if TRUE return also the esetPlot object

### Value

if `typePlot` is:

- `static`:

  - if `returnTopElements` is TRUE, and top elements can be displayed, a list with:

    - 'topElements': the top elements labelled in the plot

    - 'plot': the `ggplot` object

  - otherwise, the `ggplot` object only

- `interactive`: a `ggvis` or `rbokeh` object, depending on the `packageInteractivity` parameter
