Susceptible Infected Removed model (SIR connected)

Usage

ModelSIRCONN(
  name,
  n,
  prevalence,
  contact_rate,
  transmission_rate,
  recovery_rate
)

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

Arguments

name

String. Name of the virus

n

Number of individuals in the population.

prevalence

Double. Initial proportion of individuals with the virus.

contact_rate

Numeric scalar. Average number of contacts per step.

transmission_rate

Numeric scalar between 0 and 1. Probability of transmission.

recovery_rate

Numeric scalar between 0 and 1. Probability of recovery.

x

Object of class SIRCONN.

main

Title of the plot

...

Currently ignore.

Value

The plot function returns a plot of the SIRCONN 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.

Examples

model_sirconn <- ModelSIRCONN(
  name                = "COVID-19",
  n                   = 10000,
  prevalence          = 0.01,
  contact_rate        = 5,
  transmission_rate   = 0.4,
  recovery_rate       = 0.95
)
