Split choices_selected objects with interactions into their component variables

Split choices_selected objects with interactions into their component variables

Usage

split_choices(x)

Arguments

x

(choices_selected)
object with interaction terms

Value

a teal.transform::choices_selected() object. When x is a delayed_choices_selected object (created with delayed data), it is returned unchanged because the actual choices are not available until data is resolved at runtime.

Note

uses the regex \\*|: to perform the split.

Examples

split_choices(choices_selected(choices = c("x:y", "a*b"), selected = all_choices()))
#> $choices
#> [1] "x" "y" "a" "b"
#> 
#> $selected
#> [1] "x" "y" "a" "b"
#> 
#> $fixed
#> [1] FALSE
#> 
#> attr(,"class")
#> [1] "choices_selected"

# Also works with delayed data - returns the object unchanged
split_choices(choices_selected(variable_choices("ADSL")))
#> choices_selected with delayed data:  ADSL
#> $ choices
#>   variable_choices with delayed data: ADSL
#>   $ data
#>   [1] "ADSL"
#>   $ subset
#>   NULL
#>   $ key
#>   NULL
#> $ selected
#> NULL
#> $ keep_order
#> [1] FALSE
#> $ fixed
#> [1] FALSE
