Rename variables in a `draws`

object.

```
rename_variables(.x, ...)
# S3 method for draws
rename_variables(.x, ...)
```

- .x
(draws) A

`draws`

object.- ...
One or more expressions, separated by commas, indicating the variables to rename. The variable names can be unquoted (

`new_name = old_name`

) or quoted (`"new_name" = "old_name"`

). For non-scalar variables, all elements can be renamed together (`"new_name" = "old_name"`

) or they can be renamed individually (`"new_name[1]" = "old_name[1]"`

).

Returns a `draws`

object of the same format as `.x`

, with variables renamed
according to the expressions provided in `...`

.

```
x <- as_draws_df(example_draws())
variables(x)
#> [1] "mu" "tau" "theta[1]" "theta[2]" "theta[3]" "theta[4]"
#> [7] "theta[5]" "theta[6]" "theta[7]" "theta[8]"
x <- rename_variables(x, mean = mu, sigma = tau)
variables(x)
#> [1] "mean" "sigma" "theta[1]" "theta[2]" "theta[3]" "theta[4]"
#> [7] "theta[5]" "theta[6]" "theta[7]" "theta[8]"
x <- rename_variables(x, b = `theta[1]`) # or b = "theta[1]"
variables(x)
#> [1] "mean" "sigma" "b" "theta[2]" "theta[3]" "theta[4]"
#> [7] "theta[5]" "theta[6]" "theta[7]" "theta[8]"
# rename all elements of 'theta' at once
x <- rename_variables(x, alpha = theta)
variables(x)
#> [1] "mean" "sigma" "b" "alpha[2]" "alpha[3]" "alpha[4]"
#> [7] "alpha[5]" "alpha[6]" "alpha[7]" "alpha[8]"
