)The attr.rules parameter is used to specify the rules for how nodal
attribute values for incoming nodes should be set. These rules are only
necessary for models in which there are incoming nodes (i.e., arrivals) There
are three rules available for each attribute value:
"current": new nodes will be assigned this attribute in proportion to the distribution of that attribute among existing nodes at that current time step.
"t1": new nodes will be assigned this attribute in proportion
to the distribution of that attribute among nodes at time 1 (that is,
the proportions set in the original network for netest).
<Value>: all new nodes will be assigned this specific value, with no variation.
For example, the rules list
attr.rules = list(race = "t1", sex = "current", status = "s")
specifies how the race, sex, and status attributes should be set for incoming
nodes. By default, the rule is "current" for all attributes except status,
in which case it is "s" (that is, all incoming nodes are susceptible).
Base network models use a set of module functions that specify how the
individual nodes in the network are subjected to infection, recovery,
demographics, and other processes. Core modules are those listed in the
.FUN arguments. For each module, there is a default function used in
the simulation. The default infection module, for example, is contained in
the infection.net function.
For original models, one may substitute replacement module functions for any of
the default functions. New modules may be added to the workflow at each time
step by passing a module function via the ... argument. Consult the
New Network Models tutorial.
One may remove existing modules, such as arrivals.FUN, from the workflow
by setting the parameter value for that argument to NULL.
control.net sets the required control settings for any network model
solved with the netsim function. Controls are required for both
base model types and when passing original process modules. For an overview
of control settings for base models, consult the
Basic Network Models tutorial.
For all base models, the type argument is a necessary parameter
and it has no default.
Use param.net to specify model parameters and
init.net to specify the initial conditions. Run the
parameterized model with netsim.
