In mikeroswell/MeanRarity: Hill Diversity Estimation and Visualization

Relative abundances, given richness and distributional assumption

Description

Wrapper for qgamma, qinvgamma, and qlnorm that takes the number of species and a shape parameter and gives relative abundance estimates for each species.

Usage

try_SAD(rich, x, distr)

Arguments

rich	Integer, the total number of species in the species abundance distribution.
x	Non-negative scalar, the shape parameter for a gamma distribution.
distr	Character string, one of c("lnorm", "gamma")

See Also

qgamma, qlnorm, fit_SAD, qinvgamma

Examples

try_SAD(rich = 10, x = 0.2, distr = "lnorm")
try_SAD(rich = 10, x = 2, distr = "lnorm")

try_SAD(rich = 10, x = 0.2, distr = "gamma")
try_SAD(rich = 10, x = 2, distr = "gamma")

## Not run:  try_SAD(rich = 10, x = -1, distr = "lnorm")
try_SAD(rich = 10, x = -1, distr = "gamma")
try_SAD(rich = 10, x = 0, distr = "gamma")

## End(Not run)
