Hi All,

Is there already a helper function to allow users to easily extract the model-implied covariance matrix for the latent variables in a RAM-type model? If not, then I created one (attached). If there was already one, then I've duplicated it under possibly different implementation.

If this is useful to many people, then it could be incorporated into OpenMx at some point.
