Assign colors to groups

Given a group membership vector, each group receives a unique color such that the resulting color vector is as long as the group membership vector.

assignColorsToGroups(
  groups,
  refName = "ref",
  myColors = NULL,
  returnMap = FALSE,
  hiddenSamples = c()
)

Arguments

refName	the name of the reference group; receives gray as a color
myColors	an optional map of predefined colors for groups
returnMap	whether to return the color map together with the colors
hiddenSamples	optional vector of indices of samples to be hidden; these are assigned an invisible color

Value

a vector of colors; if returnMap is true, a vector of colors and the color map
