Bind draws objects together

Bind multiple draws objects together to form a single draws object.

Usage

bind_draws(x, ...)

# S3 method for class 'draws_matrix'
bind_draws(x, ..., along = "variable")

# S3 method for class 'draws_array'
bind_draws(x, ..., along = "variable")

# S3 method for class 'draws_df'
bind_draws(x, ..., along = "variable")

# S3 method for class 'draws_list'
bind_draws(x, ..., along = "variable")

# S3 method for class 'draws_rvars'
bind_draws(x, ..., along = "variable")

Arguments

x

(draws) A draws object. The draws format of x will define the format of the returned draws object.

...

(draws) Additional draws objects to bind to x.

along

(string) The dimension along which draws objects should be bound together. Possible values are "variable" (the default), "chain", "iteration", and "draw". Not all options are supported for all input formats.

Value

A draws object of the same class as x.

Examples

x1 <- draws_matrix(alpha = rnorm(5), beta = rnorm(5))
x2 <- draws_matrix(alpha = rnorm(5), beta = rnorm(5))
ndraws(x1)
#> [1] 5
ndraws(x2)
#> [1] 5
x3 <- bind_draws(x1, x2, along = "draw")
ndraws(x3)
#> [1] 10

x4 <- draws_matrix(theta = rexp(5))
x5 <- bind_draws(x1, x4, along = "variable")
variables(x5)
#> [1] "alpha" "beta"  "theta"
