Generic function to extract data from a simulated trajectory

Usage

trajectory(model, compartments = NULL, index = NULL, ...)

model: the object to extract the trajectory from.
compartments: specify the names of the compartments to extract data from. The compartments can be specified as a character vector e.g. compartments = c('S', 'I', 'R'), or as a formula e.g. compartments = ~S+I+R (see ‘Examples’). Default (compartments=NULL) is to extract the number of individuals in each compartment i.e. the data from all discrete state compartments in the model. In models that also have continuous state variables e.g. the SISe model, they are also included.
index: indices specifying the subset of nodes to include when extracting data. Default (index = NULL) is to extract data from all nodes.
