[R] how to create a segplot in black and white?

[Rui Barradas]

To exclude the color key use


plotBiomRatio2 <- segplot(
     reorder(factor(Species), ratioBiomass) ~ (-SEratio  ) + SEratio,
     data =  dfInOutBiom2,
     col = "black",
     level = NULL,
     #-------------- this changed
     colorkey = FALSE,
     #-------------- end
     draw.bands = FALSE,
     centers = ratioBiomass,
     [...etc...]
