draws_matrix: The draws_matrix format

Description

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

Usage

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

Value

A draws_matrix object, which has classes c("draws_matrix", "draws", "matrix").

Arguments

x

An object to convert to a draws_matrix object.

...

For as_draws_matrix(): Arguments passed to individual methods (if applicable). For draws_matrix(): 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_matrix" are matrices (2-D arrays) with dimensions "draw" and "variable". See Examples.

Examples

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

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