Title
lbl_drop_unused_val_lbls - Drop value labels not attached to any variable.
Syntax
lbl_drop_unused_val_lbls , [confirm]
| options | Description |
|---|---|
| confirm | Prompts user before removing any unused value labels |
Description
When attached to variables, value labels are an essential part of data documentation. Left unused, they create clutter and, potentially, confusion.
To eliminate any unattached value labels, drop them with lbl_drop_unused_val_lbls. To check for and inspect unattached value labels, use lbl_list_unused_val_lbls.
Options
confirm lists unused value labels and confirms whether the user indeed wants to drop them. When prompted, the user should type y for yes or n for no. With this response, the command will perform the appropriate action.
Examples
* create one variable
gen v1 = .
* define more than one value label set
label define v1 1 "yes" 2 "no", modify
label define v3 1 "oui" 2 "non", modify
label define v4 1 "evet" 2 "hayır", modify
* attach one value label, but not the others
label values v1 v1
* drop the value labels not attached (aka unused)
* if in doubt, ask first
lbl_drop_unused_val_lbls, confirm
n
* if intrepid, drop without asking
