get_rand_sad

the relative abundance of each species

the total number of individuals sampled
Randomly subsampling an RAD with replacement produces an SAD that is of a
similar functional form (Green and Plotkin 2007) but with overall species
richness equal to or less than the relative abundance distribution.
