Provides all active model state sizes from the network at the specified time step, output to a list of vectors.
prevalence.net(dat, at)The updated netsim_dat main list object.
Main netsim_dat object containing a networkDynamic
object and other initialization information passed from
netsim.
Current time step.
This network utility is used during the netsim simulation
process to efficiently query the current size of each state or compartment
in the model at any given timestep. For a two-group network, the current
state size for each group and overall is provided.
