You are not likely to find people willing to debug 15553 lines of code for you, and they are certainly not going to do it "by eye", without the datasets!

One thing that jumps out is that you start off by loading five external packages, either of which might be the true owner of the problem. Even if the actual crash hits in the stats.dll, the underlying issue could well be memory corruption occurring some time earlier. 

Things to try:

Run under Rterm in a command window instead of Rgui. That should at least tell you how far you got before the crash, maybe even a proper traceback.

Carefully try disabling parts of the code until the issue goes away. The last item removed might hold the clue. If you can cut it down to something small(-ish) and reproducible, people might be in a better position to help you.

Is it really a random crash, or does the crash point move every time you change the code slightly? If the former, you might have physical computer problems or you might be running close to your memory limit.
