find_lognormal_to_wrap_around_Xu: Find lognormal to wrap around Xu problem

In langfob/bdpg: Package For Building and Testing Biodiversity Problem Generators

Find lognormal to wrap around Xu problem

Description

Uses optimizer to search for parameters of a lognormal distribution that will have at least as many species occurring on exactly 2 patches as the given Xu problem and meet the other curve shape criteria given in the argument list.

Usage

find_lognormal_to_wrap_around_Xu(
  Xu_bdprob,
  parameters,
  desired_Xu_spp_frac_of_all_spp,
  solution_frac_of_landscape,
  desired_max_abundance_frac,
  seed_value_for_search,
  max_search_iterations,
  add_one_to_lognormal_abundances,
  search_outfile_name
)

Arguments

Xu_bdprob	a Xu_bd_problem object
parameters	parameters list for the run, usually derived from project.yaml and can have a varying number and set of elements depending on the run
desired_Xu_spp_frac_of_all_spp	numeric
solution_frac_of_landscape	numeric
desired_max_abundance_frac	numeric
seed_value_for_search	integer
max_search_iterations	integer
add_one_to_lognormal_abundances	boolean
search_outfile_name	character string

Value

Returns numeric vector of abundances
