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

pars

A character vector of parameter names.

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))
