sirmod: Gradient-function for the SIR model

In epimdr: Functions and Data for "Epidemics: Models and Data in R"

Description

Gradient-function for the SIR model

Usage

sirmod(t, y, parms)

Arguments

t	Implicit argument for time
y	A vector with values for the states
parms	A vector with parameter values for the SIR system

Value

A list of gradients

Examples

require(deSolve)
times  = seq(0, 26, by=1/10)
paras  = c(mu = 0, N = 1, beta =  2, gamma = 1/2)
start = c(S=0.999, I=0.001, R = 0)
out=ode(y=start, times=times, func=sirmod, parms=paras)
