record_attr_history: Record Attribute History

In EpiModel: Mathematical Modeling of Infectious Disease Dynamics

Record Attribute History

Description

This function records values specific to a time-step and a group of nodes. In the records, the posit_ids are converted to unique_ids which allows the recording of data for nodes that are no longer in the network by the end of the run. The records are stored in dat[["attr.history"]] where dat is the main netsim_dat class object, and can be accessed from the netsim object with get_attr_history.

Usage

record_attr_history(dat, at, attribute, posit_ids, values)

Arguments

dat	Main netsim_dat object containing a networkDynamic object and other initialization information passed from netsim.
at	The time where the recording happens.
attribute	The name of the value to record.
posit_ids	A numeric vector of posit_ids to which the measure applies. (see get_posit_ids).
values	The values to be recorded.

Details

See the "Time-Varying Parameters" section of the "Working With Model Parameters" vignette.

Value

The updated netsim_dat main list object.

Examples

## Not run: 
# This function must be used inside a custom module
dat <- record_attr_history(dat, at, "attr_1", get_posit_ids(dat), 5)
some_nodes <- get_posit_ids(dat)
some_nodes <- some_nodes[runif(length(some_nodes)) < 0.2]
dat <- record_attr_history(
  dat, at,
  "attr_2",
  some_nodes,
  rnorm(length(some_nodes))
)

## End(Not run)
