Definition of the SIR model

Description

Class to handle the SIR SimInf_model.

Details

The SIR model contains three compartments; number of susceptible (S), number of infectious (I), and number of recovered (R). Moreover, it has two state transitions,

S -- beta S I / N --> I

I -- gamma I --> R

where β is the transmission rate, γ is the recovery rate, and N=S+I+R.

Examples

## Create an SIR model object.
model <- SIR(u0 = data.frame(S = 99, I = 1, R = 0),
             tspan = 1:100,
             beta = 0.16,
             gamma = 0.077)

## Run the SIR model and plot the result.
set.seed(22)
result <- run(model)
plot(result)
