Hi Sacha,
I was referring to the BRugs package, where I usually proceed as follows:
result = BRugsFit (...)
param_samples = samplesSample("param") (1)
But (1) takes a long time for big chains. So my question was specific to
BRugs, if there an alternative way to get the samples.
Short answer: No.
Long answer: Well, samplesHistory(..., plot=FALSE) may be more
convenient for several parameters at once, but it uses samplesSample
internally, that means: no.

openbugs() mentioned by you seems to be from R2WinBUGS that I have never
used. I'll try that. Thanks for the suggestion.
Best,
Thiago

If you obtain an output object with openbugs(), e.g.:
samples<- openbugs( ... )
Then this is a list with all the parameters and samples. See
names(samples). You can obtain the samples in a list with:
samples[['sims.list']]
Is this what you mean?

Hello R users,
I have used the R package BRugs in some applications but one thing that
annoy me is the functions to retrieve samples ("samplesSample") or
summary
statistics ("samplesStats"). They take a really long time to return the
values if the size of the chains in question is moderate, for example
10.000 samples. Does this happens with every one or there is a better way
to obtain such values?
