Theta

A generic, easy-to-use and expandable implementation of a
pharmacokinetic (PK) / pharmacodynamic (PD) model based on the S4
class system. This package allows the user to read/write a
pharmacometric model from/to files and adapt it further on the fly in
the R environment. For this purpose, this package provides an
intuitive API to add, modify or delete equations, ordinary
differential equations (ODE's), model parameters or compartment
properties (like infusion duration or rate, bioavailability and
initial values). Finally, this package also provides a useful export
of the model for use with simulation packages 'rxode2' and 'mrgsolve'.
This package is designed and intended to be used with package
'campsis', a PK/PD simulation platform built on top of 'rxode2' and
'mrgsolve'.
