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, $$S \stackrel{\beta S I / N}{\longrightarrow} I$$ $$I \stackrel{\gamma I}{\longrightarrow} R$$ where \(\beta\) is the transmission rate, \(\gamma\) 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)
