1. Quoting the last lines of this message:
"PLEASE do read the posting guide 
http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code."
Otherwise we cannot help anyway.

2. This is not the BUGS mailing list.

3. I do prefer BRugs, the R package that is based on OpenBUGS, because 
it is closer to BUGS, more flexible, sometimes easier to debug, ....

Best wishes,

Hi all,

I did some analysis using package R2WinBUGS to call WinBUGS. I set the
iterations to 50000 (fairly a large number, I think), but after the program
was done,  the effective posterior samples contained only 7 draws.  I don't
know why.

By the way, I checked posterior sample size by using bugsobj$n.sims. And,
for my previous practice with WinBUGS/R2WinBUGS, no such strange thing
happend. Does anybody have some idea on what might be wrong with my model or
whatever part in this program?  Appreciate it.

Anny

Which I strongly second, not only because of the author.

On the other hand, it doesn't run under Linux (so far,
as far I know).  JAGS does
(and R2jags provides an almost identical interface as R2WinBUGS)
but is generally considerably slower than WinBUGS ...

Yes, JAGS would be nice, but I still have problems installing it under Windows.
Looks like the OS-canyon gapes between us...

Have a nice new year
