Get default model — get_default_model • photosynthesis

Get the name of the default model used for different plant ecophysiological data analysis methods implemented in photosynthesis. Currently only used for fit_aq_response2() and fit_r_light2().

Light response models:

marshall_biscoe_1980(): Non-rectangular hyperbolic model of light responses
photoinhibition(): Non-rectangular hyperbolic model of light responses with photoinhibition of k_sat at increasing Q_abs

Usage

get_default_model(.photo_fun)

get_all_models(method)

marshall_biscoe_1980(Q_abs, k_sat, phi_J, theta_J)

photoinhibition(Q_abs, k_sat, phi_J, theta_J, b_inh)

Arguments

.photo_fun: A character string of photosynthesis function to call. One of: aq_response, r_light.
method: A character string of the statistical method to use: 'ls' for least-squares and 'brms' for Bayesian model using brms::brm(). Default is 'ls'.
Q_abs: Absorbed light intensity (\(\mu\)mol m\(^{-2}\) s\(^{-1}\))
k_sat: Light saturated rate of process k
phi_J: Quantum efficiency of process k
theta_J: Curvature of the light response
b_inh: Inhibition parameter

Value

A character string with name of model.
