My question here is pure curiosity as I have found a workaround. No
urgency.
In a dataset I have, I need to replace zeros with "missing" for all
variables in the dataset.
A recent statalist exchange suggested the use of recode with a
foreach loop. That suggestion was to turn a missing value into zeros
--- the reverse of what I'm after --- so I tried to adapt the
suggestion:
recode myvar (mis = 0)
The reverse:
recode myvar (0 = mis)
But that and other similar attempts failed. The "dot" sysmiss
approach worked, so that's what I'm using now:
recode myvar (0 = .)
<CODE>
use auto,clear
local variables rep78
foreach var of varlist `variables'{
* recode `var'(3=mis) /// fails
* recode `var'(3=sysmiss) /// fails
* recode `var'(3=missing) /// fails
* recode `var'(3=`missing') /// fails
* recode `var'(3=-9999) /// works
recode `var'(3=.) /// works
}
<\CODE>
