Description Usage Arguments Details Author(s) See Also
This is a collection of utility functions called by dde.model
when
a model defined by delay differential equations is evaluated. None of these
functions is typically called directly by users.

|
parms |
A vector of primary parameters. |
derparms |
A list of derived parameters, specified in the $DERIVED block of code. |
delags |
A vector of delay parameters, typically returned by
|
codedde |
The content of the R code specified within the $DDE block in the model file. |
dosing |
A data.frame of dosing information created by
|
has.dosing |
A logical variable, indicating whether any input has to be assigned to a system state. |
dose.states |
A vector of integers, indicating in which system state one or more doses have to be assigned to. |
xdata |
A vector of times at which the system is being evaluated. |
covdata |
A matrix of covariate data extracted from the dataset. |
scale |
A vector of system scale, typically returned by
|
check |
An indicator whether checks should be performed to validate function inputs |
codelags |
The content of the R code specified within the $LAGS block in the model file. |
dde.syst
is the function which actually evaluates the system of delay
differential equations specified in the $DDE block.
dde.lags
is the function which evaluates the code specified in the $LAG
block and defines the delays at which the system needs to be computed.
