FitMultipleDynamicGrowth class

Description

The class FitMultipleDynamicGrowth has been superseded by the top-level class GlobalGrowthFit, which provides a unified approach for growth modelling.

Still, it is still returned if the superseded fit_multiple_growth() is called.

It is a subclass of list with the items:

fit_results: the object returned by modFit.
best_prediction: a list with the models predictions for each condition.
data: a list with the data used for the fit.
starting: starting values for model fitting
known: parameter values set as known.
sec_models: a named vector with the secondary model for each environmental factor.

Arguments

`x`	an instance of FitMultipleDynamicGrowth.
`...`	ignored
`y`	ignored
`add_factor`	whether to plot also one environmental factor. If `NULL` (default), no environmental factor is plotted. If set to one character string that matches one entry of x$env_conditions, that condition is plotted in the secondary axis
`ylims`	A two dimensional vector with the limits of the primary y-axis.
`label_x`	label of the x-axis
`label_y1`	Label of the primary y-axis.
`label_y2`	Label of the secondary y-axis.
`line_col`	Aesthetic parameter to change the colour of the line geom in the plot, see: `geom_line()`
`line_size`	Aesthetic parameter to change the thickness of the line geom in the plot, see: `geom_line()`
`line_type`	Aesthetic parameter to change the type of the line geom in the plot, takes numbers (1-6) or strings ("solid") see: `geom_line()`
`line_col2`	Same as lin_col, but for the environmental factor.
`line_size2`	Same as line_size, but for the environmental factor.
`line_type2`	Same as lin_type, but for the environmental factor.
`point_size`	Size of the data points
`point_shape`	shape of the data points
`subplot_labels`	labels of the subplots according to `plot_grid`.
`object`	an instance of FitMultipleDynamicGrowth
`env_conditions`	a tibble describing the environmental conditions (as in `fit_multiple_growth()`.
`times`	A numeric vector with the time points for the simulations. `NULL` by default (using the same time points as the ones defined in `env_conditions`).
`k`	penalty for the parameters (k=2 by default)

Methods (by generic)

print(FitMultipleDynamicGrowth): print of the model
plot(FitMultipleDynamicGrowth): comparison between the fitted model and the experimental data.
summary(FitMultipleDynamicGrowth): statistical summary of the fit.
residuals(FitMultipleDynamicGrowth): calculates the model residuals. Returns a tibble with 4 columns: time (storage time), logN (observed count), exp (name of the experiment) and res (residual).
coef(FitMultipleDynamicGrowth): vector of fitted parameters.
vcov(FitMultipleDynamicGrowth): (unscaled) variance-covariance matrix, estimated as 1/(0.5*Hessian).
deviance(FitMultipleDynamicGrowth): deviance of the model.
fitted(FitMultipleDynamicGrowth): fitted values. They are returned as a tibble with 3 columns: time (storage time), exp (experiment identifier) and fitted (fitted value).
predict(FitMultipleDynamicGrowth): vector of model predictions
logLik(FitMultipleDynamicGrowth): loglikelihood of the model
AIC(FitMultipleDynamicGrowth): Akaike Information Criterion
