models function

Get default model

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

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

Returns

A character string with name of model.
