Analysis of the number of Species, Genera, and Families in Samples of the Plot

Description

Provides an overview of the functions that count the number of species, genera and families for given areas of a plot. Coordinates for specific areas, random samples of areas of equal size or different shapes (rectangular only), means for the numbers of species, genera or families can be computed with these functions. spp.randarea.range is the most versitile and general function for analysing species area curves and sample number and plot size and shape effects.
