\title{Functions for manipulating jags model objects}
\description{
A \code{jags} object represents a Bayesian graphical model
described using the BUGS language.
}
\usage{
\method{update}{jags}(object, niter=1, by, \ldots)
\method{coef}{jags}(object, chain=1, \ldots)
}
\arguments{
\item{object}{a \code{jags} model object}
\item{niter}{number of iterations to update the model}
\item{by}{update frequency for progress bar. See Details}
\item{chain}{chain number to query}
\item{\ldots}{additional arguments to the call (ignored)}
}
\value{
These are methods for generic functions applied to \code{jags}
model objects.
The \code{update} function update all samplers associated with the
model by the given number of iterations. This function modifies the
original object and invisibly returns \code{NULL}.
The \code{coef} function returns a list with an entry for each Node
array that contains an unobserved Node. Elements corresponding to
observed Nodes or deterministic Nodes are given missing values.
}
\details{
Since MCMC calculations are typically long, a progress bar is displayed
during the call to \code{update}. The progress bar is refreshed every
\code{by} iterations. If R is not being used interactively then the
progress bar is suppressed.
