SimInf (version 5.0.0)

SIR: Create a SIR model

Description

Create a SIR model to be used by the simulation framework.

Usage

SIR(u0, tspan, events = NULL, beta = NULL, gamma = NULL)

Arguments

u0

A data.frame with the initial state in each node, see details.

tspan

A vector (length >= 2) of increasing time points where the state of each node is to be returned. Can be either an integer or a Date vector. A Date vector is coerced to a numeric vector as days, where tspan[1] becomes the day of the year of the first year of tspan. The dates are added as names to the numeric vector.

events

a data.frame with the scheduled events, see SimInf_model.

beta

The transmission rate from susceptible to infected.

gamma

The recovery rate from infected to recovered.

Value

SIR

Details

The argument u0 must be a data.frame with one row for each node with the following columns:

S

The number of sucsceptible in each node

I

The number of infected in each node

R

The number of recovered in each node

Examples

# NOT RUN {
## Create a 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.
result <- run(model, threads = 1, seed = 22)
plot(result)
# }
