Extract global data from a SimInf_model object

The global data is a numeric vector that is common to all nodes. The global data vector is passed as an argument to the transition rate functions and the post time step function.

Usage

gdata(model)

# S4 method for class 'SimInf_model'
gdata(model)

Arguments

model

The model to get global data from.

Value

a numeric vector

See also

ldata for retrieving local data (node-specific), and SimInf_model for the class definition and overview of model structure.

Examples

## Create an SIR model
model <- SIR(
  u0 = data.frame(S = 99, I = 1, R = 0),
  tspan = 1:5,
  beta = 0.16,
  gamma = 0.077
)

## Set 'beta' to a new value
gdata(model, "beta") <- 2

## Extract the global data vector that is common to all nodes
gdata(model)
#> beta 
#>    2
