Add color-bar to plot

colorbar(
  clut = Col(rev(rainbow(11, start = 0, end = 0.69)), alpha),
  x.range = c(-0.5, 0.5),
  y.range = c(-0.1, 0.1),
  values = seq(clut),
  digits = 2,
  label.offset,
  srt = 45,
  cex = 0.5,
  border = NA,
  alpha = 0.5,
  position = 1,
  direction = c("horizontal", "vertical"),
  ...
)
