Multiple rank-abundance curves
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.
Community data, a matrix-like object with samples in rows and species in columns. Rank-abundance curves are drawn for all selected rows (samples).
The main title (optional).
If set on
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.
