systemAge: System and pool age for constant compartment models

In SoilR: Models of Soil Organic Matter Decomposition

System and pool age for constant compartment models

Description

Computes the density distribution and mean for the system and pool ages of a constant compartmental model in matrix representation

Usage

systemAge(A, u, a = seq(0, 100), q = c(0.05, 0.5, 0.95))

Arguments

A	A constant compartmental square matrix with cycling rates in the diagonal and transfer rates in the off-diagonal.
u	A one-column matrix defining the amount of inputs per compartment.
a	A sequence of ages to calculate density functions
q	A vector of probabilities to calculate quantiles of the system age distribution

Value

A list with 5 objects: mean system age, system age distribution, quantiles of system age distribution, mean pool-age, and pool-age distribution.
