A few changes in this release of the OpenMx binary as we draw nearer to the 1.0 release and the freeze of features.
A mechanism for periodically saving checkpoint files to the local filesystem has been implemented. Using mxRun()
with "checkpoint=TRUE" will save a file with the name [modelname].omx to the current working directory every 10 minutes. Use mxOption() to customize some of the behaviors of the checkpoint file (see ?mxOption or the demo "SimpleCheckpoint").
When specifying a RAM model with an observed means vector, the expected means vector will no longer be automatically generated. See the following thread for a discussion on this new behavior.
In the upcoming weeks the developers will be working on optimizing the performance of the current feature set.
