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.

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.

# Request all free parameters in model
omxLocateParameters(model)

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