# Marker only for illustration, no statisical evidence for given significance niveaus.

signibox()
signibox(2, 3, 10, "highly significant")
signibox(4, 5, 4, "NS")
signibox(start = 3, end = 5, height = 8.5, 
  sigtext = "NS", color = "black", textsize = 2, 
  linetype = 1, textheight = 0.5, linewidth = 2)
