pdr_predict: Predict total pool, heavy isotope pool, and atom percent

In PoolDilutionR: Calculate Gross Biogeochemical Flux Rates from Isotope Pool Dilution Data

Predict total pool, heavy isotope pool, and atom percent

Description

Predict total pool, heavy isotope pool, and atom percent

Usage

pdr_predict(
  time,
  m0,
  n0,
  P,
  k,
  pool = "CH4",
  frac_P = frac_P_default(pool),
  frac_k = frac_k_default(pool)
)

Arguments

time	Vector of numeric time values (e.g. days); first should be zero
m0	total pool size at time zero, as a volume
n0	pool size of heavy isotope at time zero, as a volume
P	production rate, unit gas/unit time
k	first-order rate constant for consumption, 1/unit time
pool	Name of pool; see pdr_fractionation
frac_P	Fractionation value for production; see pdr_fractionation
frac_k	Fractionation value for consumption; see pdr_fractionation

Value

Returns a data frame with mt, nt, and AP_pred (atom percent) for each time step

Note

This is Eq. 11 from von Fischer and Hedin 2002 with a few modifications.
