Activities for modifying a source's trajectory or source object by name. Sources must be defined in the simulation environment (see add_generator, add_dataframe).

set_trajectory(.trj, sources, trajectory)

set_source(.trj, sources, object)



the trajectory object.


the name(s) of the source(s) or a function returning the name(s).


the trajectory that the generated arrivals will follow.


a function modelling the interarrival times (if the source type is a generator; returning a negative value stops the generator) or a data frame (if the source type is a data source).


Returns the trajectory object.
