The type
argument is one of the following
'birth'
By default, a new individual newI
is created, with the same characteristics of the parent I
and birth date equal to the current time. Optional code can be precised in kernel_code
.
'death'
By default, the individual I
dies. Optional code can be precised in kernel_code
.
'entry'
A new individual newI
is added to the population, and its characteristics have to be defined by the user in the entry kernel_code
.
'exit'
An individual I
exits from the population. Optional code can be precised in kernel_code
.
'swap'
The user can change the characteristics of the selected individual I
. This requires kernel_code
.
'custom'
None of the above types, the user defines kernel_code
that can act on the selected individual I
and on the population pop
.
The kernel_code
argument is a string containing some C++ code which describing the action of the event. Some of available variables in the C++ code are: t
(the current time), pop
(the current population), I
(the current individual selected for the event), newI
(the new individual if 'birth'
or 'entry'
event), the name of the model parameters (some variables, or functions, see mk_model
).
