CTFS.diversity {CTFS} | R Documentation |
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.
