How to get the correlation residuals with the new version of OpenMx?

Hi,

I recently downloaded the most recent version of OpenMx. Since then I am no longer able to get the model-implied covariance matrix, and therefore, the correlation residuals. Before, the following script would get me the correlation residuals:

residuals <- cov2cor(covmatrix) - cov2cor(modelfit$objective@expCov) round(residuals, digits=4) My data are in "covmatrix", a symmetric covariance matrix. The result of the mxRun is stored in "modelfit") This script doesn't work anymore because modelfit$objective@expCov no longer gives me the model implied covariance matrix. What do I have to type instead?

Never mind

Oops I just figured it out. All I had to do was add "info$". The following script works: residuals <- cov2cor(covmatrix) - cov2cor(modelfit$objective@info\$expCov)
round(residuals, digits=4)

Sorry!
