Extract Value/Label Levels from a Format

Returns the mappings of a ks_format object as a tidy two-column data frame with value and label.

Usage

flevels(fmt)

Arguments

fmt

A ks_format object, or a character name of a format registered in the global library.

Value

A data.frame with columns value and label. Rows are returned in the order entries appear in the format. If the format has no mappings, an empty data frame with the same columns is returned.

Details

For range-based formats, value contains the internal range key representation (for example, "0,18,TRUE,FALSE"). Use franges() to retrieve parsed range bounds.

Examples

fmt <- fnew(
  "PBO" = "Placebo",
  "D50" = "Drug A 50 mg",
  "D100" = "Drug A 100 mg"
)
flevels(fmt)
#>   value         label
#> 1   PBO       Placebo
#> 2   D50  Drug A 50 mg
#> 3  D100 Drug A 100 mg
