Function to generate a random distribution of body sizes by
drawing from a gamma distribution. Shape and rate parameters of the gamma
are estimated from the empirical data.
Usage
size_gamma(speciesData = rnorm(50, mean = 100, sd = 1))
Arguments
speciesData
a vector of body sizes or other trait measurements of
species. All values must be positive real numbers.
Value
Returns a vector of simulated body sizes as the same length as speciesData.
