create_deg_func function

Create degradation functions for known analytical solutions

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

Arguments

• spec: List of model specifications as contained in mkinmod objects
• use_of_ff: Minimum or maximum use of formation fractions

Returns

Degradation function to be attached to mkinmod objects

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)
## Not run:
