steady_state: Estimate Steady State Biomass

Description

Estimate Steady State Biomass

Usage

steady_state(x = NULL, pars = NULL, model = NULL)

Value

A named numeric value representing the estimated steady state biomass from the specified model.

Arguments

x

A litfit object. If provided, pars and model parameters are extracted from this object.

pars

A numeric vector of parameters for the model. Only needed if x is not provided.

model

A character string specifying the decomposition model. Must be one of the following: "neg.exp", "weibull", "discrete.parallel", "discrete.series", or "cont.quality2". Only needed if x is not provided.

Details

Computes the steady state biomass, as a proportion of the annual input, based on a given model fit or parameters.

Currently, the function supports a subset of decomposition models. New model support is planned for future updates.

Examples

# Example with litfit object
fit <- fit_litter(
  time = c(0,1,2,3,4,5,6),
  mass.remaining = c(1,0.9,1.01,0.4,0.6,0.2,0.01),
  model = 'neg.exp',
  iters = 250
)
steady_state(fit)

# Example with specific model and parameter values
steady_state(pars = c(6,2), model = "weibull")
