subset: Subset an MCMC object

Description

Subsets an MCMC object by its chains, iterations and/or parameters.

Usage

# S3 method for mcmcarray
subset(x, chains = NULL, iters = NULL, iterations = NULL, ...)
# S3 method for mcmcr
subset(
  x,
  chains = NULL,
  iters = NULL,
  pars = NULL,
  iterations = NULL,
  parameters = NULL,
  ...
)
# S3 method for mcmcrs
subset(
  x,
  chains = NULL,
  iters = NULL,
  pars = NULL,
  iterations = NULL,
  parameters = NULL,
  ...
)
