setNetGSEA: Creating an igraph from genes of interest and a list of gene...
In Solatar/setR:

Imports: igraph, data.table,

setNetGSEA(
  gsea,
  edgefactor = 1,
  spread = 1,
  vertexSize = 7,
  vertexShape = "pie",
  labelSize = 2,
  labelDistance = 1.7
)

`gsea`	gsea object from function seekGSEA() from the seeqR package
`spread`	number, factor to expand the plot
`vertexSize`	number, regulates the size of the nodes/vertexes of the plot
`vertexShape`	character, either "pie" (default) or "none", circle", “square”, “csquare”, “rectangle” “crectangle”, “vrectangle”, “raster”, or “sphere”
