This function draws multiple rank-abundance curves for selected samples into one diagram. If you wish to draw a simple rank-abundance curve see racurve.

Rank abundance curves or Whittaker plots (see Whittaker 1965) are used to display relative species abundance as biodiversity component. They are a means to visualise species richness and species evenness.
The axes of the diagram will be scaled according automatically. As the line type is used to differenciate between samples, a maximum of 6 curves per diagram is feasible in black/white mode.
