  y1 = y0 + 0.2,
  absolute = FALSE,
  legend = character(0),
  palette,
  lwd = 4,
  lty = 1,
  lend = "square",
  cex = 1,
  text.col = par("col"),
  font = NULL,
  text.font = font,
  title = NULL,
  title.col = text.col[1],
  title.cex = cex[1],
  title.adj = 0.5,
  title.font = 2,
  pos = 4,
  ...
)
