\title{Functions for manipulating jags model objects}
\description{
A \code{jags} object represents a Bayesian graphical model
described using the BUGS language.
}
\usage{
\method{coef}{jags}(object, chain=1, \ldots)
\method{variable.names}{jags}(object, \ldots)
list.samplers(object)
}
\arguments{
\item{object}{a \code{jags} model object}
\item{chain}{chain number to query}
\item{\ldots}{additional arguments to the call (ignored)}
}
\value{
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.
The \code{variable.names} function returns a character vector of
names of node arrays used in the model.
The \code{list.samplers} returns a named list with an entry for each
Sampler used by the model. Each element of the list is a character
vector containing the names of stochastic Nodes that are updated
together in a block at each iteration. The names of the list elements
indicate the sampling methods that are used to update each block
of Nodes.
