Description

SIR Epidemiological Model

Usage

sir(time, init_s, init_i, init_r, gamma, beta)

Arguments

time	Vector of time points at which to evaluate system
init_s	Initial proportion susceptible
init_i	Initial proportion infected
init_r	Initial proportion resistant
gamma	Transition rate from infected to resistant
beta	Transition rate from susceptible to infected

Value

Tidy data frame with three columns:

Time		Same values and units as argument time
Status		One of 'Susceptible', 'Infected', or 'Resistant'
Proportion		Proportion of population with given status at given time

Examples

t <- seq(0, 50, 0.1)
sir(time = t, init_s = 0.9999, init_i = 0.0001, init_r = 0, gamma = 0.6,
    beta = 0.08)
