u0<- {SimInf}

Update the initial compartment state u0 in each node

Description

Update the initial compartment state u0 in each node

Usage

u0(model) <- value

## S4 replacement method for signature 'SimInf_model'
u0(model) <- value

Arguments

model

The model to update the initial compartment state u0.

value

A data.frame with the initial state in each node. Each row is one node, and the number of rows in u0 must match the number of nodes in model. Only the columns in u0 with a name that matches a compartment in the model will be used.

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)

## Update u0 and run the model again
u0(model) <- data.frame(S = 990, I = 10, R = 0)
result <- run(model)
plot(result)
