Hi ya, thanks a lot everyone!! I changed rr:ii-1 to rr:(ii-1) and the code works!!! I finally get some estimates from the optimization function (i am doing a logit model with 2 segments). Thanks thanks!!! I didn't realize rr:(ii-1) and rr:ii-1 would make such a big difference, especially because the professor used rr:ii-1 in his Gauss code. I didn't realize it means so much different in R! davidr-2 wrote:
The lines below made me understand clearly. Maybe they are already in some documentation, but if not, it might help others to avoid my misunderstanding.

It will be set to the next value in the 1:10 vector the next time it comes back to the top. <snip> Duncan Murdoch
