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))
