Bivariate or multivariate correlated factors model script

I am super new to twin analyses, R, Mx and the whole shebang ... I am wondering if anyone has a script for a bivariate or multivariate correlated model. I have been using the Cholesky Decomposition, Independent Pathways and Common Pathways models to look at my multivariate data and would like to be able to at the data from a correlated factors perspective.

Any help much and greatly appreciated!
