R: Log parameters and state to disk or memory

mxComputeCheckpoint {OpenMx} | R Documentation

## Log parameters and state to disk or memory

### Description

Captures the current state of the backend. When `path` is set, the state is written to disk in a single row. When `toReturn` is set, the state is recorded in memory and returned after `mxRun`.

### Usage

    mxComputeCheckpoint(what=NULL, ..., path=NULL, append=FALSE, header=TRUE, toReturn=FALSE,
    				parameters=TRUE, loopIndices=TRUE,
      fit=TRUE, counters=TRUE, status=TRUE)

### Arguments

`what` | a character vector of algebra names to include in each checkpoint
`...` | Not used. Forces remaining arguments to be specified by name.
`path` | a character vector of where to write the checkpoint file
`append` | if FALSE, truncates the checkpoint file upon open. If TRUE, existing data is preserved and checkpoints are appended.
`header` | whether to write the header that describes the content of each column
`toReturn` | logical. Whether to store the checkpoint in memory and return it after the model is run
`parameters` | logical. Whether to include the parameter vector
`loopIndices` | logical. Whether to include the loop indices
`fit` | logical. Whether to include the fit value
`counters` | logical. Whether to include counters (number of evaluations and iterations)
`status` | logical. Whether to include the status code
