In seananderson/metafolio: Metapopulation Simulations for Conserving Salmon Through Portfolio Optimization

Return desired squared deviation between desired area and actual area under a curve

Description

The function finds the lower and upper roots (where the thermal curve crosses 0) with the uniroot function and then integrates the area under the thermal curve with the integrate function. This is useful as part of the optimization routine in optim_thermal.

Usage

thermal_area(
  max_a,
  desired_area,
  optim_temp,
  width_param,
  lower = -5,
  upper = 40
)

Arguments

max_a	Maximum Ricker a productivity value
desired_area	Desired area under the thermal curve
optim_temp	Optimal temperature
width_param	The width parameter as a numeric value
lower	Lower bound to pass to uniroot
upper	Upper bound to pass to uniroot
