plotExwas(
  object,
  ...,
  subtitles,
  color,
  exp.order,
  labels,
  show.effective = TRUE
)

...	Other objects of class ExWAS.
subtitles	(optional) Characters used as "substitle" when more than one ExWAS is given.
color	(optional) Character vector of HTML colors, labeled with family's names. Used to colore the exposures.
exp.order	(optional) Character vector of exposures used to order and subset the plot.
labels	(optional) Character vector with the labels for each exposure. It must be labeled vector.
