Class to handle the SIS SimInf_model.
Details
The SIS model contains two compartments; number of susceptible (S), and number of infectious (I). Moreover, it has two state transitions, $$S \stackrel{\beta S I / N}{\longrightarrow} I$$ $$I \stackrel{\gamma I}{\longrightarrow} S$$ where \(\beta\) is the transmission rate, \(\gamma\) is the recovery rate, and \(N=S+I\).
Examples
## Create an SIS model object.
model <- SIS(u0 = data.frame(S = 99, I = 1),
tspan = 1:100,
beta = 0.16,
gamma = 0.077)
## Run the SIS model and plot the result.
set.seed(22)
result <- run(model)
plot(result)
