I think if you put the double quote around label1, it should be OK. Try for example

egen id = group(string)
local i=1
while `i'<=2 {
preserve
keep if id==`i'
local label`i' = string[_n]
label variable id `"`label`i''"'
tab id
local i=`i'+1
restore
}

for data
+--------------+
| string |
|--------------|
1. | ad "c c" d |
2. | ced "adb" ed |
+--------------+

Then you have

ad "c c" d | Freq. Percent Cum.
------------+-----------------------------------
1 | 1 100.00 100.00
------------+-----------------------------------
Total | 1 100.00
(1 observation deleted)

ced "adb" |
ed | Freq. Percent Cum.
------------+-----------------------------------
2 | 1 100.00 100.00
------------+-----------------------------------
Total | 1 100.00


Cheers

James,

Thanks for your suggestion. Unfortunately it didn't work. The value that I am trying to assign is a string containing space, e.g. "Gross foreign direct investment (% of GDP)". Therefore I have to include the quotation marks (""). In fact the coding I send in my previous email was assigning the string values to the local macros, the problem was when I tried to label the variables using those local macros.

Best,

Rafa

If you change
local label`i' = "string[_n]"
to
local label`i' = string[_n]
it should work.
The latter assigns the value of string[_n] to label`i'.

Subject: st: labels as values of a string variable

I want to attach labels to a group of variables (varlist).

The labels that I want to use for each variable are available as
observations in one of the variables (string). I tried the following:

levels string, local(labels)
tokenize `lables'

* An error occurred because the string values contained spaces.
Therefore I
tried:

egen id = group(string)    //20 groups
local i=1
while `i'<21 {
   preserve
   keep if id==`i'
   local label`i' = "string[_n]"
   local i = `i'+1
   restore
}

When I used -di `label1'- the label names where correctly
displayed. However
when I tried to attached them to the variables using -label var- :

label var var1 "`label1'"

The label attached was "string[_n]" and not the value of it.

Many thanks,

Rafa
