rxSymInv

invobj

theta

Power of Omega, either 1 or -1 for inverse. If 0,
return an environment with all possible deriatives and Omegas
caluclated

the theta number to take the derivative. That is
d(Omega)/dTheta. When dTheta = 0, just return the Omega or
Omega^-1 matrix. Also can be 0.5. When 0.5 and pow is -1,
return -1/2*log(det(omegaInv)).

dTheta

Get Omega and Omega^-1 and derivatives

Facilities for running simulations from ordinary
differential equation (ODE) models, such as pharmacometrics and other
compartmental models.  A compilation manager translates the ODE model
into C, compiles it, and dynamically loads the object code into R for
improved computational efficiency.  An event table object facilitates
the specification of complex dosing regimens (optional) and sampling
schedules.  NB: The use of this package requires both C and
Fortran compilers, for details on their use with R please see
Section 6.3, Appendix A, and Appendix D in the "R Administration and
Installation" manual. Also the code is mostly released under GPL.  The
VODE and LSODA are in the public domain.  The information is available
in the inst/COPYRIGHTS.
