Other people may have better ideas but here is what I
would do.
I would create a temporary variable for each id to hold
the changes and then
copy them over all at once.
Ex:
egen id= group(code)
gen temporary_id = .
replace temporary_id=3 if id==1;
replace temporary_id=5 if id==2;
replace temporary_id=8 if id==3;
then:
id = temporary_id
drop temporary_id
Hope this helps,
David

Subject: st: Data management
Hi,
I have a panel data of (say) 100 countries for 10 years.
I
am trying to attach identification numbers for these
countries based on another dataset for merging purposes
later on. So, I started with
a. egen id= group(code), where "code" is the code
numbers
of these countries, e.g. ABW, AFG etc.
b. Then I am trying to replace these id-s with
replace id=3 if id==1;
replace id=5 if id==2;
replace id=8 if id==3;
But the 3rd line of the command is replacing the first
set
of id-s also. I would greatly appreciate if someone can
suggest how to take care of this.
Thanks,
Suryadipta.
