Subsets an nlists object by its parameters, chains and iterations.

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

Arguments

x

An nlists object.

chains

An integer vector of chains.

iters

An integer vector of iterations.

pars

A character vector of parameter names.

...

Unused.

Value

An nlists object.

Details

It can also be used to reorder the parameters as well as duplicate chains and iterations.

Examples

nlists <- nlists(
  nlist(a = 1, y = 3, x = 1:4),
  nlist(a = 2, y = 4, x = 4:1),
  nlist(a = 3, y = 6, x = 5:2)
)
subset(nlists)
#> $a
#> [1] 2
#> 
#> $y
#> [1] 4
#> 
#> $x
#> [1] 4 3 3 2
#> 
#> an nlists object of 3 nlist objects each with 3 numeric elements
subset(nlists, pars = "a")
#> $a
#> [1] 2
#> 
#> an nlists object of 3 nlist objects each with 1 numeric element
