  pars = NULL,
  iterations = NULL,
  parameters = NULL,
  ...
)

Arguments

x	An mcmc.list object.
chains	An integer vector of chains.
iters	An integer vector of iterations.
pars	A character vector of parameter names.
iterations	An integer vector (or NULL) of the iterations to subset by.
parameters	A character vector (or NULL) of the parameters to subset by.
...	Unused.

Details

Future versions should allow it to be reordered by its parameters.

Value

An mcmc.list object.

Examples

mcmc.list <- as_mcmc_list(nlists(
  nlist(beta = 1:2, theta = 1),
  nlist(beta = 3:4, theta = -1)
))
subset(mcmc.list, pars = "beta")
subset(mcmc.list, iters = c(1L, 1L))
