Hi R-Help!
I used R2WinBUGS and WinBUGS directly on the same model just to compare. It
seems I am still making a mistake: after running the function bugs() I tried to
plot the posteriors of the parameters by using read.bugs() to convert the output
to an mcmc object and then plot.mcmc() to plot
This is due to the following:
In bugs(), the default for thinning is
n.thin = max(1, floor(n.chains * (n.iter - n.burnin)/1000))
which is 29 for n.iter=12000 and n.burnin=2001 as in your example.
Therefore, the number of iterations used for calculation of posterior
values is
(12000-2001)/29

Thank you Peter,
for the comprehensive explanation. The reason I asked Does 'search do it?' is
that as I can run

I can run

or ls(package:methods)
which I can see by search.
I thought maybe what I see by search is all the environments
Thanks for the tip. That was already helpful. But I am still not satisfied with
the results. I now really changed n.thin to the same I had in WinBUGS. It looks
like the commands should now be the same. However, I still get differences of
