rwalkModel(obj=NULL, main=NULL,
equations=NULL, times=c(from=0, to=10, by=1),
init=NULL, parms=list(),
inputs=NULL, solver="iteration", initfunc=NULL)Arguments
obj
Unnamed arguments are regarded as objects of the corresponding
class. If obj is omitted, the new object is created from scratch.
main
The main equations of the model.
equations
The sub-models (sub-equations and of the model).
times
A vector of time steps or a vector with three
named values from, to, by specifying the
simulation time steps. The `from-to-by' form can be edited with
fixParms.
init
Initial values (start values) of the
state variable given as named vector.
parms
A vector or list (depending on the respective class) of constant
parameters.
inputs
Optional time-dependend input
variables (matrix or data frame).
solver
The solver used to integrate the model.
initfunc
The function is called by the initialize mechanism
and allows direct access and manipulation of all slots
of the object in creation
