An event object specifies dosing or other interventions that get implemented
during simulation. Event objects do similar things as data_set
,
but simpler and quicker.

events object
Required items in events objects include
time
, amt
, evid
and cmt
.
If not supplied, evid
is assumed to be 1.
If not supplied, cmt
is assumed to be 1.
If not supplied, time
is assumed to be 0.
If amt
is not supplied, an error will be generated.
If total
is supplied, then addl
will be set
to total
- 1.
Other items can include ii
, ss
, and addl
(see data_set
for details on all of these items).
ID
may be specified as a vector.
If replicate is TRUE
(default), then the events
regimen is replicated for each ID
; otherwise, the number of
event rows must match the number of ID
s entered
