Description Usage Arguments Value
Perform steps
generations for a population based on their defined breeding, survival,
and crowding parameters and the habitat surface.
The habitat.list
defines a list of habitats with a
N(m,sd) for each habitat used to determine the duration this habitat is observed.
A list of these habitat,N(m,sd) structures defines the temporal pattern of change,
and the order of change. i.e. a list of ( (H1,N1,(H2,N2), ...) defines an ordering of
habitat surface. The N(m,sd) is used to determine the time period before moving from Hi to H(i+1).
In addition, there is an implied cycling behavior since when the final (H,N(m,sd)) pattern is
used, the next habitat is (H1,N1).

|
steps |
Number of steps (generations) to excute the model |
curr.pop |
The current population as a .ppp |
move.table |
Movement table as defined by |
survive.table |
Survival table as defined by |
breed.table |
Breeding table as defined by |
habitat.list |
The list of habitats (probability) surfaces with associated N(m,sd). |
crowd.table |
The crowding table as defined by |
crowding.sigma |
Bandwidth used for density calculation for crowding |
max.dist |
Maximum distance between breeding parents |
track.ids |
Do you want to update the individual ids each generation? This is only required if you need to produce a family tree. |
trace.output |
Show a text-based trace of the model running in the console. |
A list containing the population for each generation. The initial population curr.pop
is the first element in the list.
