mcmc.convert: Conversions of MCMC objects
Description
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.Usage
as.matrix.mcmc(x, iters = FALSE)
as.matrix.mcmc.list(x, iters = FALSE, chains = FALSE)
as.array.mcmc.list(x, drop, ...)
Arguments
x
An mcmc or mcmc.list object
iters
logical flag: add column for iteration number?
chains
logical flag: add column for chain number? (if mcmc.list)
drop
logical flag: if TRUE the result is coerced to the
lowest possible dimension
