Plot species abundance distributions
Vector with species abundances (integer vector)
Additional graphical parameters used in
Plotting method, partial match to
method = "octave" a histogram showing the number
species in several abundance classes is generated. The abundance class
are a simplified version of the "octaves" suggested by Preston (1948), which
are based on log2-binning. The first abundance class includes species
with 1 individual, the second with 2, the third with 3-4, the fourth with 5-8, etc.
method = "rank" rank-abundance curve is generated with
species abundance rank on the x-axis (descending) and species abundance on
the y-axis (Hubbell 2001).
