This fetches back a list of mcmc.list (or mcmc) objects,
one for each parameter set in the model.

maxparams=99)
}

\arguments{
  \item{model}{Name of model to select.}
  \item{iterations}{Vector giving first and last cycle to extract from
    database, if omitted all iterations are fetched}
  \item{chain}{List giving chains to extract, if omitted all chains are
    fetched. }
  \item{maxparams}{A interger given the maximum number of parameter to
    be read in a parameter set.  This saves reading really big parameter
    into memory and may avoid memory problems on some PCs.
    }
}
\description{
This fetches back a list of \code{mcmc.list} (or \code{mcmc} if length
of \code{chain} is 1) objects, one for each parameter set in the model.
Note that parameter sets are typically vector or matrix valued, and
correspond to the variables in the model.
