Build a UMG from an OpenMx RAM model

Translates a reticular action model (RAM) fitted or specified with OpenMx into a UMG. Manifest variables become observed vertices and latent variables become latent vertices; nonzero entries of the asymmetric matrix A become directed dep edges (with fixed values shown for non-free paths), and off-diagonal entries of the symmetric matrix S become cov edges. This exposes the path-diagram content of a RAM specification in the UMG lexicon.

Usage

umg_from_OpenMx(object, plate_index = "i = 1, ..., N")

Arguments

object

An MxModel containing RAM matrices A, S, and F (the standard mxModel(type = "RAM") form).

plate_index

Index label for the person plate.

Value

An object of class umg.
