\usage{
\method{as.matrix}{mcmc}(x, iters = FALSE, ...)
\method{as.matrix}{mcmc.list}(x, iters = FALSE, chains = FALSE, ...)
\method{as.array}{mcmc.list}(x, drop, ...)
}
\arguments{
\item{x}{An \code{mcmc} or \code{mcmc.list} object}
\item{iters}{logical flag: add column for iteration number?}
\item{chains}{logical flag: add column for chain number? (if mcmc.list)}
\item{drop}{logical flag: if \code{TRUE} the result is coerced to the
lowest possible dimension}
\item{...}{optional arguments to the various methods}
}
\description{
These are methods for the generic functions \code{as.matrix()},
\code{as.array()} and \code{as.mcmc()}.
\code{as.matrix()} strips the MCMC attributes from an \code{mcmc}
object and returns a matrix. If \code{iters = TRUE} then a
column is added with the iteration number. For \code{mcmc.list}
objects, the rows of multiple chains are concatenated and, if
\code{chains = TRUE} a column is added with the chain number.
\code{mcmc.list} objects can be coerced to 3-dimensional arrays
with the \code{as.array()} function.
An \code{mcmc.list} object with a single chain can be coerced
to an \code{mcmc} object with \code{as.mcmc()}. If the argument
has multiple chains, this causes an error.
