These functions test whether an ERGM is duration dependent or not.
The method for NULL always returns FALSE by
convention.

is.durational(object, response = NULL, basis = ergm.getnetwork(object), ...)
TRUE if the ERGM terms in the model are duration dependent;
FALSE otherwise.
An ERGM formula, ergm_model object, or
ergm_state object.
Unused at this time.
See ergm().
is.durational(ergm_model): Test if the ergm_model has duration-dependent terms, which call for lasttoggle data structures.
is.durational(ergm_state): Test if the ergm_state has duration-dependent terms, which call for lasttoggle data structures.
