R: Summarize Model Parameters

omxLocateParameters {OpenMx} | R Documentation

## Summarize Model Parameters

### Description

Return a data.frame object summarizing the free parameters in the model.

### Usage

    omxLocateParameters(model, labels = NULL, indep = FALSE)

### Arguments

`model` | a MxModel object
`labels` | optionally specify which free parameters to retrieve.
`indep` | fetch parameters from independent submodels.

### Details

Invoking the function with the default value for the ‘labels’ argument retrieves all the free parameters. The ‘labels’ argument can be used to select a subset of the free parameters. Note that ‘NA’ is a valid possible input to the ‘labels’ argument.

### Examples

    A <- mxMatrix('Full', 2, 2, labels = c("A11", "A12", NA, NA), values= 1:4,
       free = TRUE, byrow = TRUE, name = 'A')

    model <- mxModel(A, name = 'model')

    # Request all free parameters in model
    omxLocateParameters(model)

    # Request free parameters "A11" and all NAs
    omxLocateParameters(model, c("A11", NA))
