draws_list: The draws_list format

Description

The as_draws_list() methods convert objects to the draws_list format. The draws_list() function creates an object of the draws_list format based on a set of numeric vectors. See Details.

Usage

as_draws_list(x, ...)
# S3 method for default
as_draws_list(x, ...)
# S3 method for draws_list
as_draws_list(x, ...)
# S3 method for draws_matrix
as_draws_list(x, ...)
# S3 method for draws_array
as_draws_list(x, ...)
# S3 method for draws_df
as_draws_list(x, ...)
# S3 method for draws_rvars
as_draws_list(x, ...)
# S3 method for mcmc
as_draws_list(x, ...)
# S3 method for mcmc.list
as_draws_list(x, ...)
draws_list(..., .nchains = 1)
is_draws_list(x)

Value

A draws_list object, which has classes c("draws_list", "draws", "list").

Arguments

x

An object to convert to a draws_list object.

...

For as_draws_list(): Arguments passed to individual methods (if applicable). For draws_list(): Named arguments containing numeric vectors each defining a separate variable.

.nchains

(positive integer) The number of chains. The default is 1.

Details

Objects of class "draws_list" are lists with one element per MCMC chain. Each of these elements is itself a named list of numeric vectors with one vector per variable. The length of each vector is equal to the number of saved iterations per chain. See Examples.

Examples

x1 <- as_draws_list(example_draws())
class(x1)
print(x1)
str(x1)

x2 <- draws_list(a = rnorm(10), b = rnorm(10), c = 1)
class(x2)
print(x2)
str(x2)
