create_deg_func: Create degradation functions for known analytical solutions

Description

Create degradation functions for known analytical solutions

Usage

create_deg_func(spec, use_of_ff = c("min", "max"))

Value

Degradation function to be attached to mkinmod objects

Arguments

spec

List of model specifications as contained in mkinmod objects

use_of_ff

Minimum or maximum use of formation fractions

Examples

SFO_SFO <- mkinmod(
  parent = mkinsub("SFO", "m1"),
  m1 = mkinsub("SFO"))
FOCUS_D <- subset(FOCUS_2006_D, value != 0) # to avoid warnings
fit_1 <- mkinfit(SFO_SFO, FOCUS_D, solution_type = "analytical", quiet = TRUE)
if (FALSE) {
fit_2 <- mkinfit(SFO_SFO, FOCUS_D, solution_type = "deSolve", quiet = TRUE)
if (require(rbenchmark))
  benchmark(
    analytical = mkinfit(SFO_SFO, FOCUS_D, solution_type = "analytical", quiet = TRUE),
    deSolve = mkinfit(SFO_SFO, FOCUS_D, solution_type = "deSolve", quiet = TRUE),
    replications = 2)
  DFOP_SFO <- mkinmod(
    parent = mkinsub("DFOP", "m1"),
    m1 = mkinsub("SFO"))
  benchmark(
    analytical = mkinfit(DFOP_SFO, FOCUS_D, solution_type = "analytical", quiet = TRUE),
    deSolve = mkinfit(DFOP_SFO, FOCUS_D, solution_type = "deSolve", quiet = TRUE),
