R: Generate pieces for FOCEi inner problem

.rxGenFocei {RxODE} | R Documentation

## Generate pieces for FOCEi inner problem

### Description

Generate pieces for FOCEi inner problem

### Usage

    .rxGenFocei(
      obj,
      predfn,
      pkpars = NULL,
      errfn = NULL,
      init = NULL,
      pred.minus.dv = TRUE,
      sum.prod = FALSE,
      optExpression = TRUE,
      promoteLinSens = TRUE,
      theta = FALSE,
      addProp = c("combined2", "combined1")
    )

### Arguments

`obj` | RxODE object
`predfn` | Prediction function
`pkpars` | Pk Pars function
`errfn` | Error function
`init` | Initialization parameters for scaling.
`pred.minus.dv` | Boolean stating if the FOCEi objective function is based on PRED-DV (like NONMEM). Default TRUE.
`sum.prod` | A boolean determining if RxODE should use more numerically stable sums/products.
`optExpression` | Optimize the model text for computer evaluation.
`promoteLinSens` | Promote solved linear compartment systems to sensitivity-based solutions.
`theta` | Calculate THETA derivatives instead of ETA derivatives. By default FALSE
`addProp` | one of "combined1" and "combined2"; These are the two forms of additive+proportional errors supported by monolix/nonmem: combined1: transform(y)=transform(f)+(a+b*f^c)*eps combined2: transform(y)=transform(f)+(a^2+b^2*f^(2c))*eps

### Value

RxODE/symengine environment
