thermal_area {metafolio}

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
