draws_array: The draws_array format

Description

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

Usage

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

Value

A draws_array object, which has classes c("draws_array", "draws", "array").

Arguments

x

An object to convert to a draws_array object.

...

For as_draws_array(): Arguments passed to individual methods (if applicable). For draws_array(): 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_array" are 3-D arrays with dimensions "iteration", "chain", and "variable". See Examples.

class(x1)
print(x1)
str(x1)

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