DynamicGrowth: DynamicGrowth class

In biogrowth: Modelling of Population Growth

DynamicGrowth class

Description

The class DynamicGrowth has been superseded by the top-level class GrowthPrediction, which provides a unified approach for growth modelling.

Still, it is returned if the superseded predict_dynamic_growth() is called.

A subclass of list with items:

• simulation: A tibble with the model prediction

• gammas: A tibble with the value of each gamma factor for each value of times.

• env_conditions: A list of functions interpolating the environmental conditions.

• primary_pars: A list with the model parameters of the primary model.

• sec_models: A nested list defining the secondary models.

Usage

## S3 method for class 'DynamicGrowth'
print(x, ...)

## S3 method for class 'DynamicGrowth'
plot(
  x,
  y = NULL,
  ...,
  add_factor = NULL,
  ylims = NULL,
  label_y1 = "logN",
  label_y2 = add_factor,
  line_col = "black",
  line_size = 1,
  line_type = "solid",
  line_col2 = "black",
  line_size2 = 1,
  line_type2 = "dashed",
  label_x = "time"
)

## S3 method for class 'DynamicGrowth'
coef(object, ...)

Arguments

x	The object of class DynamicGrowth to plot.
...	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_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.
label_x	Label of the x-axis.
object	an instance of DynamicGrowth

Methods (by generic)

• print(DynamicGrowth): print of the model

• plot(DynamicGrowth): predicted growth curve under dynamic conditions.

• coef(DynamicGrowth): coefficients of the model
