I'm experiencing a somewhat frustrating error in an attempt to run some bivariate Cholesky ACE models using ordinal data. Rather than use raw data inputs (there are different numbers of thresholds across variables, so coding is tricky), I have taken the "easy" way and simply created polychoric correlation matrices for the variables of interest. However, when I attempt to fit the model, R crashes.
Now, I know that the term "crash" is not usually a preferred term here, but the Rgui program (on Windows here) shuts down without reporting an error within the program. The crash generates an error report, but sending to Microsoft won't really do anything. It appears to be a front-end crash.
I am currently running R 2.11.1 and the most current OpenMx.
I have replicated this on my work machine and my laptop, but lack the debugging skills to go much further. I have tried other code with the same form, but different values, and it runs just fine. So, I am confused as to why this set of parameters causes a crash in the fashion that it does, and what I can do to prevent this in the future (or at least to know how to get the kind of information I need from R to work it out myself). As always, many thanks for your help!
(I have attached the file as I last ran it.)
