mcmcr: Manipulate MCMC Samples

#' mcmcarray
#'
#' An `mcmcarray` object is an an array where the
#' first dimension is the chains, the second dimension is the iterations
#' and the subsequent dimensions represent the dimensionality of the parameter.

#' The name `mcmcarray` reflects the fact that the MCMC dimensions,
#'  ie the chains and iterations, precede the parameter dimensions.
