Hi,
this will not work in case when one of the variables does not contain
all codes present in all other variables.
(table shows unique values only,sorted alphabetically, like Stata does it)
Var1 Var2 Var3
A B A
B C B
C
After encoding Var1 will be coded as 1=A, 2=B, 3=C; Var2: 1=B, 2=C;
Var3: 1=A,2=B, which is in all probability not what moleps islon
wanted.
In general one must find a union of all possible values, then encode.
Practically this is probably easier to solve by reshaping the data to
the long format, encoding the single string variable, and then
reshaping back. If there are a few values to label, and those are
known a priori, I would hardwire them into the program and label
manually.
Best regards,

Well, if they share the same values, then the -encode- will lead to a
redundancy because technically you would need only one -label- so that

webuse hbp2, clear

foreach var in `r(varlist)'{

desc

you can reuse it with the -label- option to -encode-...

Subject: st: -encode- help..
I've got 30 different text variables that all have the same possible
values. Is there an easy way to encode all 30 variables using the same
label or do I have to do it manually. Also is it possible, somehow, to
specify stata to start encoding with tha value 0 instead of 1 ?
Best wishes,
Moleps
