# )a one-sided ergm()-style formula with the terms to be evaluated
NetSeries() LHS only arguments to specify time-varying parameters. See N() term operator in the ergm.multi for details. lm formula may reference .Time for the network's time index, .TimeID for the its index in the network series (where the initial network is 1 and the first modelled network is 2), and .TimeDelta for the time elapsed between the network and the immediately previous network in the series.
This term accepts a model formula and produces the corresponding model for a network constructed by taking the dyads that have changed between time steps.
ergmTerm for index of model terms currently visible to the package.
