subset {mcmcr}

Subset an MCMC object

Description

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

Usage

## S3 method for class 'mcmcarray'
subset(x, chains = NULL, iters = NULL, iterations = NULL, ...)

  x,
  chains = NULL,
  iters = NULL,
  pars = NULL,
  iterations = NULL,
  parameters = NULL,
  ...
)

## S3 method for class 'mcmcrs'
subset(
  x,
