Title

     labdeval -- Define value labels matching variable names


Syntax

     Define new value labels matching variable names

        labdeval varlist # "label" [# "label" ...] [, modify replace
define(lblname)]


     Copy existing value labels

        labdeval [varlist] , copy[(lblname)] [replace]


     Attach value labels in memory to same-named variables

        labdeval [varlist]


Description

    labdeval defines value labels matching variable names. Value labels are
    attached to same-named variables in the dataset.

    Specifying integer-to-text mappings defines value labels and attaches
    them to varlist, using variable names as value label names.

    Omitting integer-to-text mappings (and not specifying option copy)
    attaches already defined value labels in memory to same-named variables.
    If varlist is not specified it defaults to all numeric variables in the
    current dataset.


Options

    modify modifies existing value labels. See label define.

    replace allows existing value labels to be redefined. See label define in
        Stata 11.0 or higher.

    define(lblname) defines a single value label, lblname, and attaches it to
        all variables in varlist. Specifying define is the same as combining
        the label define and label values commands.

    copy[(lblname)] copies existing value labels.  If specified, value label
        lblname is copied and attached to variables in varlist using
        variables' names as value label names.  Omitting lblname copies each
        variable's value label and attaches it to the respective variable
        using its name. Think of copy as renaming each variable's value label
        to match the variable name. Old value labels are, however, not
        dropped from memory.


Examples

        . sysuse nlsw88 ,clear

    Define one value label set (i.e integer-to-text mappings) and attach it
    to some variables using their names as value label names.

        . labdeval never_married south c_city 1 "yes" 0 "no"
        . describe

    Define one value label, yesno, and attach this label to the variables.

        . labdeval never_married south c_city 1 "yes" 0 "no" , define(yesno)
        . describe never_married south c_city

    Now reverse the above. That is, make a copy of value label yesno and
    attach it to variables using their names as value label names.

        . labdeval never_married south c_city ,copy(yesno)
        . describe never_married south c_city

    Attach a copy of each variable's value label to that variable, using its
    name as value label name.

        . labdeval ,copy replace
        . describe
