== Labels ==

Variable and value labels are defined using the '''`label`''' command.

{{{
label variable foo "yes or no?"
label define yesno 1 "Yes" 0 "No"
label values foo yesno
}}}

See [[Stata/Label|here]] for more options.

Numeric values can be  quickly prepended to value labels using the '''`numlabel`''' command.

{{{
numlabel foo, add mask("#. ")
}}}

}}}
