[R] elements from 'sem' function

[andre tavares correa dias]

Hi, 
I would like to print elements from sem (structural equation modeling) 
function (e.g., model-reproduced covariance matrix (C); estimated asymptotic 
covariance matrix of parameter estimates (cov)). 

How can I  do this? 

Thanks, 
André
