Conversions of MCMC objects
These are methods for the generic functions as.matrix(),
as.array() and as.mcmc().
as.matrix() strips the MCMC attributes from an mcmc
object and returns a matrix. If iters = TRUE then a
column is added with the iteration number. For mcmc.list
objects, the rows of multiple chains are concatenated and, if
chains = TRUE a column is added with the chain number.
mcmc.list objects can be coerced to 3-dimensional arrays
with the as.array() function.
An mcmc.list object with a single chain can be coerced
to an mcmc object with as.mcmc(). If the argument
has multiple chains, this causes an error.
