div_rand_rect

Get mean and standard deviation of diversity indices in several equally
sized subplots of a community

Simulation, analysis and sampling of spatial
biodiversity data (May, Gerstner, McGlinn, Xiao & Chase 2017)
<doi:10.1111/2041-210x.12986>.
In the simulation tools user define the numbers of
species and individuals, the species abundance distribution and species
aggregation. Functions for analysis include species rarefaction
and accumulation curves, species-area relationships and the distance
decay of similarity.
