The official maintainers were dismissive when I suggested there were some
problems I could fix with the then implementation of polr. I haven't looked
at it since, sorry.

You can skip my question about s0 though, I found where it is being used,
but I still struggle with the code and convergence problem.
I also found something here

Hello,
I am trying to use this fix for the convergence problem in polr, but I don't
seem to get the change of code right. I redefine the function polr by the

Dear R-users,
When you perform "run line or selection" / "Ctrl + R" in a script window
then the cursor of the script window does not go to the next line but at a
place further downwards.
R windows version 11 does the correct job (= goes to the next line) but
version 12 does not.
Is this correct ?
Note that that the enhancements in my original post solve the unresolved
problem of Chaehyung Ahn (22 Mar 2005) whose data I reproduce:
y,x,lx
0,3.2e-02,-1.49485
0,3.2e-02,-1.49485
0,1.0e-01,-1.0

1,3.
The start value generation code in polr is also known to fail quite
frequently. For example, against the Iris data as recently posted to this
list by blackscorpio ( Sep 6, 2010).

That's bad. There's no reason to suppose beta[pc+1L] is larger than
-100 or that the cumulative sum is smaller than 100. For pr

Thanks for your reply.
That doesnot help
Any other suggestions?

You could try JAGS. According to the website it is 'an engine for the
BUGS language that runs on Unix'. It runs on Mac OS X and has an
interface with R (rjags).

Hello,
I recently changed from Win XP to Mac OS X (10.5.1).
Is there a way to run Bugs (in any version) in R (R version 2.6.0
(2007-10-03)) on this platform?

Hi All
I can specify whatever inits, it has no effect on the estimation. I am
replicating a textbook example. The result is completely trash, having
estimates
of -58.7 (sd=59.3), where it should be closer to an ml estimate of 0.585
(SE=0.063).
The two chains within one run are different, but
