StochasticGrowth {biogrowth} R Documentation

## StochasticGrowth class

### Description

The class StochasticGrowth has been deprecated by class GrowthUncertainty, which provides less misleading name.

Still, it is still returned if the deprecated predict_stochastic_growth() is called.

The StochasticGrowth class contains the results of a growth prediction under isothermal conditions considering parameter unceratinty. Its constructor is predict_stochastic_growth().

It is a subclass of list with the items:

• sample: parameter sample used for the calculations.

• simulations: growth curves predicted for each parameter.

• quantiles: limits of the credible intervals (5%, 10%, 50%, 90%, 95%) for each time point.

• model: Model used for the calculations.

• mus: Mean parameter values used for the simulations.

• sigma: Variance-covariance matrix used for the simulations.

### Usage

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

## S3 method for class 'StochasticGrowth'
plot(
x,
y = NULL,
...,
line_col = "black",
line_size = 0.5,
line_type = "solid",
ribbon80_fill = "grey",
ribbon90_fill = "grey",
alpha80 = 0.5,
alpha90 = 0.4
)


### Arguments

 x The object of class StochasticGrowth to plot. ... ignored. y ignored 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() ribbon80_fill fill colour for the space between the 10th and 90th quantile, see: geom_ribbon() ribbon90_fill fill colour for the space between the 5th and 95th quantile, see: geom_ribbon() alpha80 transparency of the ribbon aesthetic for the space between the 10th and 90th quantile. Takes a value between 0 (fully transparant) and 1 (fully opaque) alpha90 transparency of the ribbon aesthetic for the space between the 5th and 95th quantile. Takes a value between 0 (fully transparant) and 1 (fully opaque).
