SIR model

SIR model

Usage

ModelSIR(name, prevalence, transmission_rate, recovery_rate)

# S3 method for class 'epiworld_sir'
plot(x, main = get_name(x), ...)

Arguments

name

String. Name of the virus

prevalence

Double. Initial proportion of individuals with the virus.

transmission_rate

Numeric scalar between 0 and 1. Virus's rate of infection.

recovery_rate

Numeric scalar between 0 and 1. Rate of recovery_rate from virus.

x

Object of class SIR.

main

Title of the plot

...

Additional arguments passed to graphics::plot.

Value

• The ModelSIR function returns a model of class epiworld_model.

• The plot function returns a plot of the SIR model of class epiworld_model.

Details

The initial_states function allows the user to set the initial state of the model. In particular, the user can specify how many of the non-infected agents have been removed at the beginning of the simulation.
